The new limits of the neutrinoless $({\mu }^{-},e^{-})$ conversion branching ratio

Abstract

The nuclear physics dependence of the exotic $({\mu }^{-},e^{-})$ conversion branching ratio $R_{\mu e^{-}}$ for the experimentally most interesting nuclei ${}^{208}Pb$ and ${}^{48}Ti$, is investigated in various nuclear models. The results thus obtained are combined with the new experimental limits extracted at PSI for these nuclei to put bounds on the elementary particle parameters entering $R_{\mu e^{-}}$ such as intermediate neutrino masses and mixing angles as well as relevant parameters of intermediate supersymmetric particles (masses and mixing of s-fermions and neutralinos).
