lα→3lβ in minimal R-symmetric supersymmetric Standard Model
Abstract
Lepton flavor violation decays are channels which may lead to fundamental discoveries in the forthcoming years and this makes it an exciting research field for beyond the Standard Model (SM) searches. In this work, we present an analysis of the lepton flavor violation decays lα→3lβ in Minimal R-symmetric Supersymmetric Standard Model. The prediction for BR(lα→3lβ) depends on the off-diagonal entries of the slepton mass matrix. The contributions to Wilson coefficients can be classified into Higgs penguins, photon penguins, Z penguins and box diagrams. It shows the contribution from Z penguins dominates the predictions for BR(lα→3lβ), and the contributions from Higgs penguins and box diagrams play different roles in different decay channels. The theoretical predictions for BR(lα→3lβ) can reach the future experimental limits, and the channels are very promising to be observed in near future experiment.
