Abstract: 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....

Abstract: In this talk, we will discuss electroweak triplet contribution to SO(10) leptogenesis. The main result is that as long as triplet mass is near the
right-handed neutrino mass scale, this contribution can dominate, making it essential in assessing the viability of SO(10) leptogenesis scenarios.

Abstract: 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...

Abstract: When we assume dark matter interacts with one particle in the Standard Model, we often do not realize that through loops and effective interactions, that same dark matter model usually, automatically, interacts with many other parts of the Standard Model as well.

Abstract: The neutrino flavor oscillation, discovered and confirmed through mid 2000s is a firmly established phenomenon. Since the flavor oscillation occurs due to the fact that the flavor and mass eigenstates differ, it requires the Standard Model to be modified. Precision measurements of the neutrino properties to reflect their non-zero mass into the...

Abstract: The cosmic neutrino background is the last missing piece of the early Universe's thermal history. Its direct detection would be a monumental milestone for the fields of cosmology and particle physics. We recently proposed that cosmic rays can scatter off the cosmic neutrino background throughout the history of the Universe, yielding a flux of...

Abstract: Hot plasma in astrophysical objects provides an ideal place for the production of heavy axion-like particles (ALPs). We show that a fraction of these ALPs could stream out of the photosphere and subsequently decay into two photons that can be potentially detected on or near the Earth. In particular, we estimate the photon flux originating from the...

Abstracts: Extra-dimensional models where Kaluza-Klein particles mediate interactions of a dark sector with the Standard Model particles have recently found a renewed interest.

The existence of relic neutrino background is a strong prediction of the Big Bang cosmology. But because of their extremely small kinetic energy today, the direct detection of relic neutrinos remains elusive. On the other hand, we know very little about the nature of dark matter. In this work, we are putting constraint on the overdensity of the cosmic neutrino background by using them as the...
Axions or axion-like particles (ALPs) are hypothetical particles predicted by various BSM theories, which also make one of the dark matter candidates. If ALPs exist in nature, the CMB photons as they pass through galaxy clusters will convert to ALPs (of mass range

We present a new approach to the numerical evaluation of the effects of non-cold relics on the evolution of cosmological perturbations. The Boltzmann hierarchies used to compute the contributions of these relics to the stress-energy tensor are replaced with a set of integral equations. These integral equations take the form of convolutions and are solved iteratively coupled with Einstein's...
