Limits on R-parity non-conservation in MSSM with gauge mediated   supersymmetry breaking from the neutrinoless double beta decay
  The R-parity non-conservation phenomenology within the minimal supersymmetric standard model with gauge mediated supersymmetry breaking has been studied. New constraints on the lepton number violating constant $\lambda_{111}^\prime$ were imposed by non-observability of the neutrinoless double beta decay. We find that $\lambda_{111}^\prime$ depends strongly on the effective supersymmetry breaking scale $\Lambda$ only and deduce limits which are much stronger than those previously found in literature.
