Erice: INTERNATIONAL SCHOOL OF NUCLEAR PHYSICS, 47th COURSE

Neutrinos play a major role in the core-collapse supernova mechanism. In the supernova core, the neutrino density is so large, that neutrino self-interaction dominates the flavor evolution with major implications on the supernova mechanism, neutron-star kicks, and the nucleosynthesis of the elements heavier than iron. Our work advances the understanding of flavor conversion in core-collapse supernovae by means of multi-dimensional simulations of the neutrino kinetics. We find a very rich phenomenology, shaped by the streaming of neutrinos and their collisions with the surrounding medium.
