Description:

During a core-collapse supernova, a large number of neutrinos are emitted, which carry away a major fraction of the binding energy of the star. These neutrinos undergo flavor conversions on their way, and these are known to play a very important role in core-collapse supernova explosions. Deep within the stellar interior, neutrino density is so large that neutrino-neutrino interactions take place, giving rise to "collective oscillations" occurring with a rate much larger than the usual resonant flavor conversions. In this talk, I would like to discuss some of the interesting aspects of these rapid flavor conversions, and the impact they can have on supernova explosions and nucleosynthesis.
