Supernovae as laboratories for neutrino properties

Understand

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.
