摘要：

Neutrinoless double beta decay (0 nu beta beta) 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 R-p-MSSM couplings imposed by the current experimental limit on the 0 nu beta beta decay half-life of Ge-76. (C) 1999 Published by Elsevier Science B.V.
