Low-energy photon-neutrino inelastic processes beyond the Standard Model

Abstract

We investigate in this work the leading contributions of the MSSM with R-parity violation and of Left-Right models to the low-energy five-leg photon-neutrino processes. We discuss the results and compare them to the Standard Model ones.
