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

Abstract

Neutrinoless double-beta decay within Minimal Supersymmetric Standard Model with gauge mediated supersymmetry breaking is considered. Limits on R-parity breaking constant $\lambda _{111}^\prime$ coming from non-observability of 0νββ in ⁷⁶Ge are found. The dependence of $\lambda _{111}^\prime$ on different parameters at the messenger scale M are shown, with special attention paid to nuclear part of calculations. We have found that $\lambda _{111}^\prime$ strongly depends on the effective supersymmetry breaking scale Λ only and deduced limits imposed on this non-standard parameter by the germanium experiment.
