Supernovae as laboratories for neutrino properties

Abstract

The present thesis aims to be an analysis of various aspects of neutrino phenomenology in two different scenarios. On the one hand, we address the study of non-standard neutrino interactions (NSI) in accelerator and reactor terrestrial experiments. On the other hand, we discuss the propagation of supernova (SN) neutrinos, taking into account the recent developments showing the importance that neutrino background may have in their evolution. This effect, neglected for a long time, may be of capital importance when trying to understand the neutrino signal from a future galactic SN. Our SN neutrino analysis is presented both in absence and presence of NSI.
