Effects of non-factorizable metric on neutrino oscillation inside supernova

Abstract

In this paper we construct the interaction potential between the dense supernova core and neutrinos due to the exchange of light radions in the Randall-Sundrum scenario. We then show that the radion exchange potential affects the neutrino oscillation phenomenology inside the supernova significantly if the radion mass is less than around 1 GeV. In order that the Bethe-Wilson mechanism for heating the envelope and r-process neucleosynthesis be operative, the radion mass must be greater than 1 GeV. Bounds on the radion mass of the same order of magnitude can also be derived from TASSO and CLEO data on B decays.
