Minimal supersymmetric standard model with the gauge mediated supersymmetry breaking and the neutrinoless double-beta decay

Neutrinoless double-beta decay within Minimal Supersymmetric Standard Model with gauge mediated supersymmetry breaking is considered. Limits on R-pari ty breaking constant lambda'(111) coming from non-observability of 0v beta beta in Ge-76 are found. The dependence of lambda'(111) on different parame ters at the messenger scale M are shown, with special attention paid to nuc lear part of calculations. We have found that lambda'(111) strongly depends on the effective supersymmetry breaking scale Lambda only and deduced limi ts imposed on this non-standard parameter by the germanium experiment.
