| Abstract: | Neutrino flavor evolution out of a core-collapse supernova is a very nonlinear and rich phenomenon. Large neutrino-neutrino interaction in a dense neutrino medium results in a number of neutrino flavor instabilities which can cause large neutrino flavor transformation. In this talk I will discuss some of these instabilities, and I will show how one can understand them using some intuitive picture. I will also talk about a recently discovered flavor instability which tentatively breaks spherical symmetry out of supernova (if we have such a symmetry!), the so called "multi-azimuth angle flavor instability". Finally, I will present some of our new findings which show that even with this new neutrino flavor instability, spherical symmetry seems to be a good symmetry for the inverted hierarchy. | |
