At finite temperatures, a precise treatment of thermal resummations is essential, as bosonic fields encounter significant infrared issues that can compromise standard perturbative approaches. The Partial Dressing (or the tadpole...

The COHERENT collaboration made the first measurement of coherent elastic neutrino nucleus scattering (CEvNS) in 2017 using a low-background, 14.6-kg CsI[Na] detector at the Spallation Neutron Source (SNS). We have also measured CEvNS using a 24-kg argon scintillation calorimeter and an 18-kg array of Ge PPC detectors. These measurements are part of a multi-target campaign to measure CEvNS...

I will present a new opportunity for sub-GeV dark matter (DM) detection using large-volume neutrino detectors. DM-electron scattering in an observatory can excite or ionize target molecules, which then produce light that can be detected by the photomultiplier tubes (PMTs). While individual DM scatterings are undetectable, the aggregate rate from many independent scatterings can be isolated...

The Accelerator Neutrino Neutron Interaction Experiment (ANNIE) is a 26-ton gadolinium-doped water Cherenkov detector located at the Booster Neutrino Beam at Fermilab. ANNIE's primary physics goal is to measure the neutron multiplicity from neutrino-nucleus interactions in water, improving our understanding of neutrino interactions and helping reduce systematic uncertainties in future neutrino...

The capture of dark matter in stars provides a cosmic laboratory in which to study the nature of dark matter particles and their interactions under extreme conditions. We discuss the capture of dark matter in neutron stars and white dwarfs, and the heating caused by the subsequent thermalization and annihilation of that dark matter. We find that most of the dark matter’s kinetic energy is...

LSND and MiniBooNE have provided longstanding and statistically significant evidence of anomalous electron-like excesses. This has led to very significant theoretical and experimental activity aimed at understanding the origin of the signals. Recent results from MicroBooNE have sharpened the focus of these efforts and point towards the genuine possibility of new physics, with the possible...

I will highlight recent significant improvements in the sensitivity of ongoing direct detection experiments, especially in the MeV to GeV dark matter mass range. I will interpret these results in the context of the light dark matter theoretical landscape and motivate the work theorists need to do as these experiments increasingly plumb the depths of direct detection parameter space.

One of the many probes for Beyond Standard Model (BSM) studies is the search for Charged Lepton Flavor Violation (CLFV). The Mu2e experiment at Fermilab will search for the neutrinoless muon-to-electron conversion in the nuclear field. In Aluminum, the experimental signature of this process is a 104.97 MeV mono-energetic electron conversion. The Mu2e experiment plans to measure the ratio of...

Whether neutrinos are Majorana or Dirac in nature is an important open question in modern particle physics, which could provide insight on the matter-antimatter asymmetry in the universe. The observation of Neutrinoless Double Beta Decay (0νββ), a hypothesized Beyond Standard Model decay, would conclusively establish the Majorana nature of neutrinos and demonstrate lepton number violation. The...

SNO+ is a multi-purpose, low-background neutrino detector located at SNOLAB, Canada. Currently filled with liquid scintillator, its physics programme includes measurements of solar, reactor, geo-, and potential supernova neutrinos. Preparations are underway to load natural tellurium into the scintillator to enable a search for neutrinoless double beta decay (0νββ) in tellurium-130. This talk...

This presentation explored how the difference between interacting and non-interacting integrated two-particle correlation functions in finite volume can be related to infinite volume scattering phase shifts through an energy-weighted exponential integral, exp(-Et). Notably, the difference in integrated finite volume correlation functions converges rapidly to its infinite volume limit as the...

The long-running search for particle dark matter via an annually-modulating WIMP-nucleon interaction has received important updates in recent years with new results from the ANAIS-112 and COSINE-100 experiments. In this paper, we quantify the tension between the reported DAMA signal and ANAIS-112 and COSINE-100 in two different ways. The first is based on the effective field theory of a Dirac...

There are many possible reasons that we have not yet detected dark matter: it could be very weakly interacting, too light to trigger conventional detectors, or very massive and thus rare. But another possibility is that dark matter may scatter predominantly inelastically with Standard Model particles. In a typical model, elastic scattering is absent at tree level, and a relatively light dark...
