Resumen

We present a new contribution of the R-parity-violating (Rp) supersymmetry (SUSY) to neutrinoless double beta decay (0νββ) via the pion exchange between decaying neutrons. The pion coupling to the final state electrons is induced by the Rp SUSY interactions. We have found this pion-exchange mechanism to dominate over the conventional two-nucleon one. The latter corresponds to direct interaction between quarks from two decaying neutrons without any light hadronic mediator like πmeson. The constraints on the certain Rp SUSY parameters are extracted from the current experimental 0νββ-decay half-life limit. These constraints are significantly stronger than those previously known or expected from the ongoing accelerator experiments.
