Title: Supernovae as laboratories for fundamental neutrino physics

Speaker: Dr. Manibrata Sen, Max Planck Institute for Nuclear Physics, Heidelberg

Abstract: During a core-collapse supernova (SN), a large number of neutrinos are emitted, carrying away a major fraction of the binding energy of the star. These neutrinos are the only way to probe the dense conditions existing within a dying star. Deep within the stellar interior, neutrino density is so large that neutrino self-interactions start becoming important, leading to "collective flavour oscillations", with fascinating consequences for the spectra measured at the Earth. A future galactic SN would also allow us to probe fundamental neutrino properties like decay, non-standard neutrino interactions, extra species of sterile neutrinos, and so on. In this talk, I would like to discuss some of these aspects and highlight how a galactic SN could act as the ultimate laboratory to probe some of the fundamental neutrino properties.
