TALK: A 6D Jeans Analysis of the Sagittarius Dwarf Spheroidal Core
TALK: A 6D Jeans Analysis of the Sagittarius Dwarf Spheroidal Core
10:00 AM - 10:45 AM
Author and Speaker: Isabelle Goldstein Abstract: The stellar kinematics in dwarf galaxies can provide a wealth of information about its underlying dark matter distribution. Line of sight velocity dispersion measurements from six classical dwarf galaxies can be used to show that axion-like particles with masses of order m ~ 10−22 eV are inconsistent with the potential distribution in classical dwarf galaxies unless the hierarchical assembly of the Milky Way did not trace the mean evolution of Milky Way size halos. However, line of sight velocity constraints alone are subject to degeneracies between central dark matter density and stellar velocity anisotropy. Using Gaia DR3 data, we examine the kinematics of the central core of the Sagittarius (Sgr) dwarf spheroidal galaxy which includes proper motions and line-of-sight velocities for member stars in addition to their projected positions. We extract a sample of bright stars that are high-probability members of Sgr. We obtain a velocity anisotropy of βa=−2.24±1.99, which implies a system with tangentially-biased orbits. Proper motions and complete position information could be used to break the existing velocity anisotropy and central density degeneracy; however without accurate distances to these stars, a 6D Jeans analysis cannot be performed. We use new observations obtained with the Magellan/MIKE spectrograph to measure distances and line-of-sight velocities for RR Lyrae and red clump stars with the Sgr core to perform a full 6D Jeans analysis.

TALK: Phenomenology of forbidden dark matter decay
2:00 PM - 2:45 PM
Author and Speaker: Debasish Borah Abstract: The visible part of the present Universe is composed of matter or baryons only with negligible trace of antimatter. As the Universe is expected to start out with as much antimatter as matter, the present observation has led to the longstanding puzzle of baryon asymmetry of Universe. Another intriguing puzzle is the presence of non-luminous or dark matter in the present Universe contributing more than five times the visible matter to the total energy budget. This talk will discuss the impact of forbidden decays of particles in the early Universe enabled by finite-temperature effects on simultaneous generation of dark matter and baryon asymmetry. It will also touch upon additional phenomenological implications like gravitational waves, primordial black holes, large neutrino asymmetry etc. depending upon the particular model implementation.

TALK: The MAGIS-100 Experiment and a Future Kilometer-scale Atom Interferometer
9:00 AM - 9:45 AM
Author and Presenter: Dylan Temples Abstract: The dearth of signals unambiguously attributable to WIMP dark matter motivates exploring new parameter space, particularly the ultra-light dark matter (ULDM) regime, where the signal is not scattering events but wave phenomena. The proliferation of quantum technologies has enabled searches for ULDM at previously inaccessible sensitivity. One such technology is atom interfer- ometry which can measure time-dependent fluctuations in the energy spacing of atoms as well as in the light-travel time across the apparatus, enabling searches for ULDM and gravitational waves, respectively. In this talk, I will review the science case for long baseline atom interferometers, such as MAGIS-100 at Fermilab, provide an update on the experiment’s status, and discuss the need for a future, kilometer-scale atom interferometer which would achieve unprecedented sensitivity to ULDM and gravitational waves in the “Mid-Band”region between LIGO and LISA.

Author: Deepak Sathyan Co-Authors: Bhaskar Dutta, Aparajitha Karthikeyan, Doojin Kim, Hyunyong Kim Presenter: Deepak Sathyan Abstract: We propose a novel method to obtain sensitivity to dark mediators and dark sectors at the LHC with masses of ∼ 10 MeV − 10 GeV, providing complementarity with short baseline beam dump experiments. For this talk, we consider dark photons, which can be produced at the LHC from neutral meson decays, bremsstrahlung off baryons, or directly produced in correlation with a jet. We then consider visible decays to muon pairs as the signal channel and provide methods to control backgrounds. We show a range of sensitivities dependent on various estimates of backgrounds and different signal threshold requirements.

TALK: Inelastic Dark Matter Freeze-In and Indirect Detection
1:30 PM - 2:15 PM
Author and Presenter: Douglas Tuckler Abstract: Inelastic dark matter is a well-motivated benchmark for freeze-out and freeze-in production. In the freeze-in regime, if the mass splitting between the two dark matter states is small enough, the heavy dark matter state can be cosmologically long-lived and makes up half of the DM abundance at present time. If the mass splitting is lower than an MeV, the heavier dark matter state can only decay to photons and generates an indirect detection signal that can be observed with X-ray telescopes. In this talk, we consider inelastic dark matter with a dark photon mediator such that the heavier state decays to three photons. This photon spectrum can be detected by X-ray telescopes such as INTEGRAL/SPI, and we will show that indirect detection can access parameter space of dark photons that is currently unconstrained by other experiments.

TALK: Dark Matter Catalyzed Baryon Destruction
1:15 PM - 2:00 PM
Authors: Yohei Ema, Robert McGehee, Maxim Pospelov Presenter: Robert McGehee Abstract: WIMP-type dark matter may have additional interactions that break baryon number, leading to induced nucleon decays which are subject to direct experimental constraints from proton decay experiments. In this talk, we analyze a possibility of continuous baryon destruction, deriving strong limits from the dark matter accumulating inside old neutron stars, as such a process leads to excess heat generation. We construct the simplest particle dark matter model that breaks baryon and lepton numbers separately but conserves B − L. Virtual exchange by DM particles in this model results in di-nucleon decay via nn → nν¯ and np → ne+ processes.

TALK: Exploring Low-Energy Microphysics Relevant to Particle Sensing with Quantum Devices
2:15 PM - 3:00 PM
Author and Presenter: Ryan Linehan Abstract: The search for low-mass dark matter and coherent neutrino scattering has placed an emphasis on developing particle detectors with energy thresholds below 1 eV. As this energy scale is below the electronic bandgap for common detector materials, low-threshold detection largely relies on the ability to sense phononic excitations in cryogenic devices, often using superconducting thin film sensor architectures. To confidently use these phonon-sensing architectures for detection, it is imperative to understand the low-energy microphysical response of both the substrate and superconductor to particle impacts. This challenge is compounded by the increasing adoption of ultra-sensitive superconducting quantum sensor architectures, whose susceptibility to on-chip en- vironmental noise motivates dedicated exploration of the microphysical systems producing this noise. In this talk, we discuss aspects of this low-energy response that are relevant to operation of superconducting quantum sensors in a detection mode, and the HEP-inspired tools being devel- oped to model and characterize them.

TALK: Primordial Gravitational Waves from Phase Transitions During Reheating
2:30 PM - 3:15 PM
Author and Presenter: Fazlollah Hajkarim Abstract: We study primordial gravitational waves (GWs) generated from first-order phase transitions (PTs) during cosmic reheating. Using a minimal particle physics model, with a general parametrization of the inflaton energy density and the evolution of the Standard Model temperature, we explore the conditions under which PTs occur and determine the corresponding PT parameters. We find that, in certain cosmological scenarios, PTs can be delayed and prolonged compared to the standard post-inflationary evolution. Finally, incorporating these PT parameters, we compute the resulting GW spectrum while accounting for the uncertainties related to cosmic reheating.

TALK: Nonlinear Dynamics and Dark Matter Abundance of a Light QCD Axion

Indiana University

1:00 PM - 1:45 PM
Author and Presenter: Raymond Co Abstract: We investigate the field dynamics of the ZN QCD axion, a variant of the QCD axion that couples to N copies of the Standard Model. Contributions from N − 1 dark sectors and the visible sec- tor QCD lead to an exponentially suppressed axion mass and a time-dependent periodic potential. The potential minimum is at θ = π before the QCD phase transition. After the phase transition, this point becomes a hilltop and multiple minima develop with only one of them actually solving the strong CP problem. The resultant non-trivial field dynamics, such as rotations over potential barriers and oscillations from the hilltop, give rise to parametric resonance production of axions. We perform the first lattice simulations of the axion field evolving through the QCD phase transi- tion in an expanding universe. We find that nonlinear effects significantly impact the axion’s relic abundance and final settling point. We show the viable parameter space in which this light QCD axion can simultaneously constitute all of dark matter and solve the strong CP problem.

TALK: Enhanced Dark Matter Abundance from First-Order Phase Transitions
10:00 AM - 10:45 AM
Author and Speaker: Rouzbeh Allaverdi Abstract: I discuss a novel scenario to obtain the correct relic abundance for thermally under-produced dark matter. This scenario utilizes a strongly first-order phase transition that gives rise to dark matter mas. Freeze-out in the broken phase can yield the desired abundance in the entire region currently allowed by observational bounds and theoretical constraints. The accompanying gravitational waves are strong enough to be detected by many upcoming and proposed experiments. This, in tandem with dark matter indirect searches, provides a multi-messenger probe of such models. Positive signals in the future can help reconstruct the potential governing the phase transition and shed light on an underlying particle physics realization.

TALK: The Radio Synchrotron Background - New Particle Processes?
1:00 PM - 1:45 PM
Author and Speaker: Jack Singal Abstract: It has become apparent that the background brightness level of diffuse radio emission on the sky and its level of anisotropy is significantly higher than those which can result from known classes of astrophysical radio sources. In contrast to the more well-known photon backgrounds at microwave, infrared, optical/UV, X-ray, and gamma-ray wavelengths, where the levels of brightness and anisotropy at least roughly match those expected from known cosmological and astrophysical sources, the "radio synchrotron background" at radio wavelengths provides clear motivation for considering new sources and new particle-based emission mechanisms, including those from the dark sector. This talk will summarize the current understanding of the radio synchrotron background and some of the proposed particle-based emission mechanisms.

In this talk, we will present a novel solution to this conundrum in terms of dark matter (DM) scattering in the Earth's crust. We show that intermediate dark-sector particles that decay into muons are copiously produced when high-energy (∼100 PeV) DM propagates through a sufficient amount of Earth overburden. To address the non-observation of similar events at IceCube, we will demonstrate via two examples of weakly coupled long-lived dark sector scenarios that are sourced from a high-luminosity blazar. We calculate the corresponding dark sector cross sections, lifetimes, and blazar luminosities required to yield one event at KM3NeT, satisfy all the lab-based constraints, and also predict the number of IceCube events for these parameters that can be tested very soon.

1:00 PM - 1:45 PM
Author and Speaker: Baishan Hu Abstract: Ab Initio Nuclear Calculations for Dark Matter-Nucleus and Neutrino-Nucleus Scattering Over the past decades, ab initio nuclear calculations have made dramatic progress, especially reaching heavy mass nuclei such as 208Pb [1]. This means that it becomes possible to obtain first-principles computation (with quantified uncertainties) of quantities that even reside in the heavy-mass region. The quantities include these relevant for astrophysics and searches for physics beyond the Standard Model. In this talk, I will present a conceptual introduction to modern ab initio nuclear theory. Then, I will focus on recent advances in ab initio calculations of nuclear re- sponses for dark matter-nucleus [2] and neutrino-nucleus elastic and inelastic scattering. Finally, I will present our recent investigation of the ATOMKI anomaly using ongoing proton beam dump neutrino experiments [3]. [1]. Ab initio predictions link the neutron skin of 208Pb to nuclear forces. B.S. Hu, et al. Nat. Phys. 18, 1196 (2022). arXiv:2112.01125v1 (2021). [2].

3:00 PM - 3:45 PM
Authors: Christopher Cappiello and Tansu Daylan Presenter: Christopher Cappiello Abstract: The search for dark matter is one of the crucial open problems in both particle physics and cosmol- ogy. If dark matter scatters with Standard Model particles, it could accumulate inside the Earth and begin to annihilate, producing heat within the Earth’s core. While past work has been done on the effect that this heat would have once it reached the surface, we model the flow of heat through the Earth’s core by numerically solving the heat equation to model dark matter’s effect on the interior of the planet. We compute how long it takes for the core to come into thermal equilibrium and show that for a wide range of dark matter parameters, a substantial fraction of the inner core would be melted by dark matter annihilation. Our analysis produces new limits on dark matter annihilating in the Earth, points out important new effects that must be considered when studying planetary heating by dark matter, and suggests new dark matter observables that could be searched for in exoplanet populations.

Author and Presenter: Pearl Sandick Abstract: Cosmologically stable, light particles that came into thermal contact with the Standard Model in the early universe may persist today as a form of hot dark matter. For relics with masses in the eV range, their role in structure formation depends critically on their mass. We trace the evolution of such hot relics and derive their density profiles around cold dark matter halos, introducing a framework for their indirect detection. Applying this framework to axions — a natural candidate for a particle that can reach thermal equilibrium with the Standard Model in the early universe and capable of decaying into two photons — we establish stringent limits on the axion-photon coupling using current observations of dwarf galaxies, the Milky Way halo, and galaxy clusters.

TALK: Primordial Black Holes as Dark Sector Factories
10:00 AM - 10:45 AM
Author and Presenter: Jae Hyeok Abstract: In this talk, I present the potential use of primordial black holes (PBHs) as probes of the dark sector. Through Hawking radiation, black holes emit all particle species with masses below their Hawking temperature, providing a unique and gravitationally universal production mechanism. PBHs can reach Hawking temperatures of up to tens of MeV, enabling the emission of dark sector particles with masses up to this energy scale. By analyzing the gamma-ray spectrum from PBHs, we can probe dark sector particles that produce observable photon signals. Moreover, by studying the mass distribution of evaporating PBHs, it may be possible to access even heavier dark sector particles, including those without any direct couplings to the visible sector.

TALK: Scalar Relics from the Big Bang
1:00 PM - 1:45 PM
Author and Presenter: David Cyncynates Abstract:Motivated by the unexplained origins of dark matter and the cosmological constant, fifth-force experiments provide an important avenue to address major open questions in physics. These ex- periments take place at low energies, probing interactions among atoms, nucleons, or electrons in atomic energy levels, and are agnostic to the UV origin of any new force. However, such interac- tions, if present, lead to dynamics in the early Universe that can have cosmological implications. In this talk, I will compute the effect of the early Universe plasma on the scalar field, accounting for the full structure of the Standard Model—spontaneous symmetry breaking, dimensional trans- mutation, and the running of gauge couplings. We will see that the resulting relic abundance of the fifth-force-carrying scalar field is largely independent of how it couples to the Standard Model, ultimately pointing to a cosmologically preferred region of experimental parameter space.

TALK: Shedding Infrared Light on QCD Axion and ALP Dark Matter with JWST
2:00 PM - 2:45 PM
Author and Presenter: Ranjan Laha Abstract: James Webb Space Telescope (JWST) has opened up a new chapter in infrared astronomy. Be- sides the discovery and a deeper understanding of various astrophysical sources, JWST can also uncover the non-gravitational nature of dark matter (DM). If DM is QCD axion or an eV-scale Axion-like particle (ALP), it can decay into two photons in the infrared band. This will produce a distinct line signature in the spectroscopic observations made by JWST. Using the latest NIRSpec IFU spectroscopic observations from JWST, we put the strongest bound on the photon coupling for QCD axion/ ALP DM in the mass range between 0.47 and 2.55 eV. In particular, we are able to probe a new mass range for ALP DM between ∼ 0.47 eV to 0.78 eV beyond what can be probed by globular cluster observations. We constrain well-motivated and UV complete models of QCD axion and ALP DM, including predictions from some models derived from string theory and/ or various Grand Unification scenarios. Future JWST observations of DM-rich systems with a better understanding of the astrophysical and instrumental backgrounds can thus enable us to potentially discover QCD axion and ALP DM.

TALK New Ideas for Leptogenesis
TALK New Ideas for Leptogenesis
1:30 PM - 2:15 PM
Authors: Peisi Huang, Tao Xu, Kairui Zhang Presenter: Peisi Huang Abstract: In this talk, I will discuss two new mechanisms for leptogenesis. In the first scenario, we introduce a temperature-dependent coupling between the right-handed neutrino and Standard Model parti- cles. This coupling experiences suppression at high temperatures and becomes sizable when the lepton asymmetry washout processes are Boltzmann-suppressed. Such a feature ensures that the washout rates remain consistently below the Hubble expansion rate, preserving all lepton asymme- try generated in the decay of right-handed neutrinos. In the second scenario, We explore flavored resonant leptogenesis embedded in a neutrinophilic 2HDM. Successful leptogenesis is achieved by the very mildly degenerate two heavier right-handed neutrinos~(RHNs) N2 and N3 with a level of only ΔM32/M2∼(0.1%−1%). The lightest RHN, with a MeV-GeV mass, lies below the sphaleron freeze-out temperature and is stable, serving as a dark matter candidate. The model enables TeV- scale leptogenesis while avoiding the extreme mass degeneracy typically plagued conventional resonant leptogenesis. Baryon asymmetry, neutrino masses, and potentially dark matter relic den- sity can be addressed within a unified, experimentally testable framework.

TALK: Effective field theory for radiative corrections to charged-current processes: neutron decay, Vud, and gA. Hadronic uncertainty in neutral currents
Oleksandr Tomalak
10:00 AM - 10:45 AM
Author and Presenter: Oleksandr Tomalak Abstract: We study radiative corrections to low-energy charged-current processes involving nucleons, such as neutron beta decay and (anti)neutrino-nucleon scattering within a top-down effective-field-theory approach. First, we match the Standard Model to the low-energy effective theory valid below the weak scale, specifying the scheme dependence of the Wilson coefficients. We evolve the resulting effective coupling down to the hadronic scale using renormalization group equations. To evaluate radiative corrections at scales of the neutron decay, we perform matching to heavy-baryon chiral perturbation theory and subsequently, below the pion-mass scale, to a pionless effective theory, evolving the effective couplings all the way down to the scale of the electron mass, relevant for beta decay. We provide a representation for hadronic corrections in terms of infrared finite convolutions of simple kernels with the single-nucleon matrix elements of time-ordered products of two and three quark bilinears (vector, axial-vector, and pseudoscalar). Using our new result for the radiative corrections, we update the extraction of the largest Cabibbo-Kobayashi-Maskawa matrix element Vud from the neutron decay. I also refine the treatment of hadronic uncertainties in low-energy neutral-current processes, significantly reducing the current error estimate. These improvements have direct implications for all neutral-current interactions at low energies, including parity-violating electron scattering, elastic (anti)neutrino-electron scattering, coherent elastic (anti)neutrino-nucleus scattering, and atomic parity violation.

Seodong Shin

10:45 AM - 11:30 AM
Speaker: Seodong Shin Abstract: For the first time, we comprehensively examine the potential of a neutral current interaction of reactor neutrino with C emitting a 3.685 MeV photon to identify the origin of the 5 MeV bump in reactor antineutrino spectra observed through the inverse beta decay (IBD) process. This anomaly may be due to new physics, reactor antineutrino flux inaccuracies, or IBD systematics. The 3.685 MeV photon released during the de-excitation of C to its ground state is observable in liquid scintillator detectors. Remarkably, we confirm the powerfulness of our proposal by completely ruling out a new physics scenario explaining the bump from the existing NEOS data. We also explore the potential of current and forthcoming experiments, including solar neutrino studies at JUNO, pion and muon decay-at-rest experiments at OscSNS, and isotope decay-at-rest studies at Yemilab, to measure the cross section precisely enough to distinguish the expected bump and the theoretical flux models via our channel.

Author: Doojin Kim Abstract: The MiniBooNE low-energy excess remains one of the most prominent anomalies in neutrino experiments, with recent MicroBooNE results reporting a mild excess in the single-photon channel. We propose new scenarios involving light dark matter and/or neutrinos that can simultaneously explain both the MiniBooNE and MicroBooNE excesses. Our framework introduces photons produced via 2-to-3 scattering processes between neutrinos or dark matter and nuclei, mediated by light particles. We identify viable regions in parameter space consistent with current constraints and highlight that these scenarios can be probed by upcoming experimental data.

representations connecting to the loop diagram, we ensure that only the effective dipole operator involving the non-Abelian part of the photon -- the neutral gauge boson -- is generated. Crucially, the corresponding mass diagram, obtained by removing the external gauge boson leg, vanishes. We provide explicit UV completions that implement this mechanism and yield neutrino magnetic moments as large as from TeV-scale new physics.

TALK: Measuring the Cosmic Ray Spectrum with Next-Generation Neutrino Detectors
Stephan Meighen-Berger
(
The University of Melbourne
)
10:00 AM - 10:45 AM
Author: Stephan Meighen-Berger Abstract: In this talk, we will discuss how upcoming kiloton-scale neutrino detectors, like Hyper-Kamiokande, can be used to measure the primary cosmic ray spectrum. Unlike traditional balloon or satellite missions that offer limited spatial and temporal coverage, large neutrino detectors provide full-sky monitoring over extended periods. By analyzing the atmospheric neutrinos produced in cosmic ray interactions, we show that these detectors can distinguish between competing models of the cosmic ray spectrum, even in the presence of uncertainties in neutrino cross sections and hadronic cascades. This is achieved by using a new method for reconstructing the primary cosmic ray spectrum from neutrino data, reducing flux uncertainties from ~20% to just 7%. This improved precision not only enhances our understanding of cosmic rays but also potentially boosts sensitivities of key neutrino studies, such as oscillation parameters. As an example, I will discuss a hypothetical sin²θ₂₃ measurement and how the reduction of the cosmic ray uncertainty can potentially double Hyper-K's precision. These results demonstrate how neutrino observatories are poised to play a central role in advancing both cosmic ray and neutrino physics.

TALK: Can we observe new neutrino oscillation phenomenon with Standard Model physics?
Shirley Li
(
UC Irvine

9:45 AM - 10:30 AM
Author and Presenter: Shirley Li Abstract: Standard calculations of neutrino oscillation are predicated on the assumption that neutrinos’ wave packets maintain coherence throughout their propagation. Effects associated with neutrino wave packet decoherence—specifically, damping of the oscillation probabilities—were previously con- sidered unobservable in terrestrial experiments. However, recent claims suggest that if sterile neu- trinos exist, we could observe decoherence effects in terrestrial experiments. To test these claims, one must compute the neutrino wave packet size for a given source. In this talk, I will discuss our efforts to determine the wave packet size for neutrinos produced in accelerator-based experi- ments. We demonstrate that it is feasible to compute this value through a well-defined framework accompanied by precise input parameters.

TALK: Interplay of Nuclear and New Physics with Low-Energy Neutrino Sources
Vishvas Pandey

2:30 PM - 3:15 PM
Author: Vishvas Pandey Abstract: Low-energy neutrino sources, such as those from stopped pion or core-collapse supernova, interact with target nuclei in detectors through either coherent elastic or inelastic scattering processes. These interactions provide valuable insights into various Standard Model and Beyond the Standard Model phenomena, with significant implications for nuclear physics, particle physics, and astrophysics. The precision of coherent elastic scattering, where the nucleus remains in its ground state, depends on the accuracy of the underlying weak form factor of the nucleus. In contrast, inelastic scattering, where neutrinos excite the target nucleus to low-lying nuclear states, involves complex nuclear structures and dynamics and are quite poorly constrained. In this talk, I will present an overview of the field, highlight recent advancements, and outline future directions.

3:15 PM - 4:00 PM
Speaker: Takuya Okawa Abstract: The question of whether neutrinos are Dirac or Majorana remains open. This is mainly because almost all of the accessible neutrinos, such as laboratory neutrinos and neutrinos of astrophysical origin, are ultra-relativistic, erasing signatures that distinguish Dirac from Majorana neutrinos. We thus consider heavy neutrinos and discuss the possibility of distinguishing their Dirac versus Majorana nature. In particular, we allow a heavy neutrino to decay into another neutrino and an intermediate particle, which subsequently decays into the Standard Model particles. Then, we analyze the angular distribution of decay products for both Dirac and Majorana heavy neutrinos.

TALK: Does the 220 PeV Event at KM3NeT Point to New Physics?
Vedran Brdar

Oklahoma State University

9:00 AM - 9:45 AM
Speaker Vedran Bridar Abstract: The KM3NeT collaboration recently reported the observation of KM3-230213A, a neutrino event with an energy of 220 PeV, nearly an order of magnitude more energetic than the highest-energy neutrino in IceCube's catalog. Despite its larger effective area and longer data-taking period, IceCube has not observed events of similar energies which implies a 2–3σ tension, depending on the type of neutrino source. The 220 PeV neutrino detected at KM3NeT traversed approximately 147 km through rock and sea, whereas neutrinos from the same location in the sky would cross only about 14 km of ice to reach IceCube. In this talk, I will show how this difference in propagation distance helps to resolve this tension. Specifically, I will present a scenario where the source emits sterile neutrinos that partially convert to active neutrinos via oscillations. I will discuss two mechanisms: one where a new-physics matter potential induces a resonance in sterile-to-active transitions, and another involving off-diagonal neutrino non-standard interactions. In both cases, oscillations over 100 km enhance the active neutrino flux at KM3NeT with respect to the flux at IceCube.

2:30 PM - 3:15 PM
Author: Dibya S. Chattopadhyay Co-author: Vedran Brdar Abstract: The KM3NeT collaboration recently reported the observation of KM3-230213A, a neutrino event with an energy of 220 PeV. The absence of any PeV events in IceCube, despite its larger effective area and longer data-taking period, suggests an anomaly, with a tension quantified between approximately ~2 and 3.5, depending on the assumed source model. This implies a possible new physics origin for the event KM3-230213A. Meanwhile, the anomalous upgoing events detected by the ANITA experiment, with energies near 1 EeV and arrival angles implying traversal through thousands of kilometers of Earth, similarly hint at a possible origin involving new physics in the neutrino sector. We investigate two mechanisms that could simultaneously account for both anomalies: one in which a new matter potential induces a resonance in sterile-to-active neutrino transitions, and another involving off-diagonal neutrino non-standard interactions. Using the arc lengths traversed by the ANITA events, we identify the relevant parameter space and explore how matter-enhanced oscillations between the sterile and active sectors may help explain both the ANITA and KM3NeT observations. Overall, we examine the possibility that recent ultra-high-energy neutrino observations have already observed physics beyond the Standard Model.

3:15 PM - 4:00 PM
Presenter: Adrian Thompson Abstract: The standard candles of electroweak observables can be studied through the lens of neutrino-electron scattering as a purely weak process. We project the sensitivity of a neutrino detector situated around 100 meters away in the plane of a high energy muon storage ring or muon collider with , 1.5, and 5 TeV muon beam energies, providing a highly energetic and highly intense source of electron and muon (anti)neutrinos. We find world-leading sensitivity to the weak couplings at the sub-percent level is possible, with sensitivity to the Standard Model prediction for the neutrino charge radius. Finally, we show that sensitivity to the momentum transfer dependence of at the level, within a single dataset and configuration of the proposed experiment, is possible.

TALK: Exploring Quantum Statistics for Dirac and Majorana Neutrinos using Spinor-Helicity techniques
Innes Bigaran
(
Fermilab and Northwestern University

1:15 PM - 2:00 PM
Speaker: Innes Bigaran Abstract: Recently, there has been interest in the applicability of quantum statistics to distinguish Dirac from Majorana neutrinos in multi-neutrino final states. In particular, debate has arisen over the validity of the Dirac-Majorana confusion theorem in these processes, i.e., that any distinction between the Dirac and Majorana processes goes to zero as the neutrino mass goes to zero. Here we approach this problem equipped with spinor-helicity methods generalized for massive Dirac and Majorana fermions. We explicitly calculate all helicity amplitudes for the decay of a light scalar particle to two neutrinos and two oppositely charged leptons. This allows us to pinpoint the crucial steps which could lead to claims of a violation of the confusion theorem. We show that if the correct anti-symmetrization of Dirac to Majorana amplitudes is used, identification of which is clear in this framework, and all relevant contributions are appropriately summed, a scalar decay into two charged leptons and two neutrinos satisfies the Dirac-Majorana confusion theorem.

2:45 PM - 3:30 PM
Speaker: Diksha Garg Abstract: The all-sky very-high-energy (–GeV) atmospheric muon flux has been measured by IceCube. The higher end of this energy range is expected to come from the prompt component. IceCube also measures the atmospheric muon neutrino flux at high energies; however, due to the dominant contribution from astrophysical sources, it is only able to place an upper limit on the prompt atmospheric muon neutrino flux. In this work, we present a new evaluation of the prompt atmospheric muon flux, incorporating for the first time an intrinsic charm component in the colliding nucleons. The inclusion of intrinsic charm enhances the forward production of hadrons such as, and, which subsequently decay into muons and muon neutrinos. We demonstrate that the intrinsic charm contribution leads to an increase in both the prompt muon and muon neutrino fluxes. To model intrinsic charm production, we consider the Regge-based ansatz that is implemented within the MCEq framework for lepton flux calculations. Finally, we explore the challenges in reconciling predictions that simultaneously match IceCube’s measured atmospheric muon flux and its upper bound on the prompt muon neutrino flux.
