Flavor oscillation modes in dense neutrino media
Presented by Huaiyu Duan (UNM)
Dense neutrino media exist in both the early Universe and in core-collapse supernovae. One of the most significant advances in physics in the last two decades is the confirmation and measurements of neutrino flavor oscillations, which is the first solid piece of evidence of physics beyond the standard model of particle physics. Because of the neutrino-neutrino scattering potential, flavor oscillations in a dense neutrino medium can exhibit collective behaviors. Because collective neutrino oscillations are such complicate phenomena, some assumptions about symmetry such as the isotropy of neutrino fluxes in the early Universe are universally adopted. However, it was recently pointed out that such assumptions are not necessarily true for neutrino oscillations. In this talk I will provide a simple and intuitive explanation for this discovery.
