Description

"Neutrinos from dense environments, non-radiative neutrino decay and the diffuse supernova neutrino background"

M. Cristina Volpe (CNRS/INP and APC, Paris)

In this talk I will first describe the frontiers of our knowledge on neutrino flavor evolution in dense media - core-collapse supernovae, binary neutron star mergers, early universe - and mention connections to other domains, in particular quantum information theory and computing [1,2]. How neutrino change flavor, in astrophysical and cosmological environments, is tightly linked to known and unknown neutrino properties. I will focus on the case of non-radiative neutrino decay and its importance for future observations, in particular the upcoming discovery of the diffuse supernova neutrino background and its interpretation [3,4].
