New Supersymmetric Contributions to Neutrinoless Double Beta Decay.

Abstract
The neutrinoless double beta () decay is analyzed within the Minimal Supersymmetric Standard Model with explicit R-parity violation ( MSSM). We have found new supersymmetric contributions to this process and give the complete set of relevant Feynman diagrams. Operators describing 0+ 0+ nuclear transitions induced by the supersymmetric interactions of the MSSM are derived. These operators can be used for calculating the decay rate applying any specific nuclear model wave functions.
