μ-e conversion in nuclei in the left-right supersymmetric model
Description
We investigate the contributions to μ-e conversion in nuclei in a supersymmetric model with left-right symmetry, motivated by the new data on neutrino oscillations. We study the dependence of the conversion rate on the various parameters of the model, and show that light-mass or large tanβ scenarios are severely restricted. We analyse the effect of several popular mechanisms of neutrino mixing on the conversion rate as well as the influence of the right-handed scale on the conversion rate. We compare the conversion rate to the branching ratio for μ→eγ and discuss their relative accessibility at future experiments, their sensitivity to various parameters of the model, as well as their relative importance in providing signals for new physics.
