The physics surrounding neutrino mass and neutrino interactions presents key research opportunities in elementary particle physics, both in theory and in experiment. Paralleling the developments in those fields, advances in observational astrophysics and cosmology promise unprecedented precision in the measurement of cosmological quantities. In many cases, those quantities are shaped by how...
We discuss the implications in a core-collapse supernova environment of a light dark matter particle that sees the standard model exclusively through its interaction with neutrinos. We consider the case of a light dark matter candidate which couples to neutrinos through a heavy mediator, and examine parameter regimes of interest from the point of view of supernova cooling, neutrino decoupling,...
The existence of light sterile neutrinos / heavy neutral leptons below the electroweak scale is of great interest from the points of view of both theory and experiments. We will discuss some theoretical motivations for the existence of such light states in extended frameworks as well as the wide variety of phenomenology that they can give rise to.
The sensitivity of future neutrino experiments to oscillation parameters and BSM physics is highly dependent on the reduction of theoretical nuclear modeling systematics within the quasielastic regime. The usage of highly phenomenological or even classical nuclear models of Fermi motion, as well as nontrivial and inconsistent reweighting schemes, only adds to these woes. Also, many neutrino...
Atmospheric neutrino experiments can show the "oscillation dip" feature in data, due to their sensitivity over a large $L/E$ range. In experiments that can distinguish between neutrinos and antineutrinos, like INO, oscillation dips can be observed in both these channels separately. We present a data-driven approach $-$ that uses the asymmetry in the up and down events, binned in the...
The mechanism of the core-collapse supernova is not completely established and continues to fuel a lot of active research. With the advent of DUNE and HyperKamiokande, the neutrino burst from the next galactic core-collapse supernova will allow us to observe the development of the explosion in real time, during the first crucial ten seconds. The task is to understand how to read this signal,...
