Signatures of Supernova Neutrino Oscillations into Extra Dimensions

We consider the mixing of muon and tau neutrinos with sterile fermion fields propagating in extra dimensions in the context of core collapse supernova physics, extending the analysis of the electron neutrino case done in a previous work. We show that the potentially dramatic modifications to the sup...

description We consider the mixing of muon and tau neutrinos with sterile fermion fields propagating in extra dimensions in the context of core collapse supernova physics, extending the analysis of the electron neutrino case done in a previous work. We show that the potentially dramatic modifications to the supernova evolution are prevented by a mechanism of feedback, so that no severe bounds on the parameters of the extra dimensions need to be imposed. Nevertheless, the supernova core evolution is significantly modified. We discuss the consequences on the delayed explosion mechanism and the compatibility with the SN1987A signal. Then, for the cases of both nu_{mu,tau} and nu_e mixing with bulk fermions, we analyse the distinctive features of the signal on Earth.
