Title: Low energy neutrino phenomenology and new interactions at neutrino detectors

Speaker: Dr. Newton Nath (INFN Bari)

Abstract: Despite its remarkable success in explaining a large collection of phenomena observed in nature, the Standard Model (SM) of particle physics fails to address several fundamental issues, e.g., non-zero neutrino mass, a viable dark matter (DM) candidate, and the strong CP problem, to name a few. In this talk, starting with a brief overview, we shall first discuss the symmetry-based approaches to explain neutrino mixing patterns, and later their consequences will be addressed for the upcoming neutrino oscillation experiment DUNE. Besides this, we shall talk about "exotic" neutrino interactions, possible sub-leading effects originating from physics beyond the SM, in a U(1)^\prime model and their impact on CE\nuNS experiments will be analyzed. Later, we shall discuss the interplay between neutrino and the dark sector. Starting with the light DM, we shall talk about various consequences for the CE\nuNS, “Lifetime Frontier”, as well as neutrinoless double beta experiments. Considering axions, our aim will be to explain the nature of neutrinos using the Peccei-Quinn symmetry. Finally, we shall discuss the sensitivity reach of the JUNO experiment in order to detect solar axions in a model-independent way.
