Description
Understanding of supernova neutrinos has seen a qualitative change recently. It has been understood that neutrinos are not only affected by collisions with stellar matter, but also due to collisions among themselves. This effect, while ordinarily negligible, plays a crucial role in supernovae. The essential result is that close to the production surface, neutrino and anti-neutrinos of all energies undergo flavor conversion collectively. In this talk, I will review SN neutrino phenomenology, with an emphasis on collective oscillations and its possible signatures at neutrino detectors.
