Stellar energy loss rates in the pair-annihilation process beyond the standard model

Abstract

We calculate the stellar energy loss due to neutrino-pair production in $e^{+}{e}^{-}$ annihilation in the context of a 331 model, a left-right symmetric model and a simplest little Higgs model in a way that can be used in supernova calculations. We also present some simple estimates which show that such process can act as an efficient energy loss mechanism in the shocked supernova core. We find that the stellar energy loss is almost independent on the parameters of the models in the allowed range for these parameters. This work complements other studies on the stellar energy loss rate in $e^{+}{e}^{-}$ annihilation.
