Description

Cracking the Supernova Neutrino Code

Abstract:
A supernova emits gargantuan numbers of neutrinos and antineutrinos of all flavors with different luminosities and energy spectra. Due to neutrino oscillations, these different neutrinos mix with each other. To what extent does this mixing occur? Superficially, this is an elementary exercise in two-level quantum mechanics. In practice, it turns out to be a very difficult (and still unanswered) question. I will review recent work on this problem and explain why it is important to answer this question in order to know why stars explode, how heavy elements are created in stars, and how to interpret the next galactic supernova signal.
