Improved bounds on SUSY accompanied neutrinoless double beta decay

High Energy Physics - Phenomenology 2009-10-31 v2

Abstract

Neutrinoless double beta decay induced by light Majorana neutrino exchange between two decaying nucleons with squark/slepton exchange inside one and W exchange inside the other nucleon (so-called vector-scalar exchange) gives stringent limits on R-parity violating interactions. We have extended previous work by including the tensor contribution to the transition rate. We discuss the improved limits on trilinear \Rp -MSSM couplings imposed by the current experimental limit on the \znbb\znbb decay half-life of 76^{76}Ge.
