Effects of a nonfactorizable metric on neutrino oscillation inside a supernova - art. no. 083003

In this paper we construct the interaction potential between the dense supe rnova core and neutrinos due to the exchange of light radions in the Randal l-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 for the Bethe-Wilson mechanism for heating the envelope and r-process neucleosynthesis to be op erative, the radion mass must be greater than 1 GeV. Bounds on the radion m ass of the same order of magnitude can also be derived from TASSO and CLEO data on B decays.
