Description
The lepton-flavor-violating(LFV) interactions are extremely suppressed in Standerd Model, making this process an excellent way to explore new physics. In this work, we revisit the LFV interactions in R-parity violating SUSY model, with renormalization group running effects(RGEs) from high to low energy scales. The LFV processes $\mu-e$ conversion, $\mu \to e\gamma$ and $\mu \to 3e$ impose upper limits on the 15 combinations of $|\lambda'_{ijk}\lambda'^{*}_{mnk}|$ and 6 combinations of $|\lambda_{ijk}\lambda_{mnk}|$ for trilinear RPV couplings. In certain cases, the RGEs can improve the constraints by $\sim 80 \%$. In the near future, the $\mu-e$ conversion experiments will provide the most stringent constraints, which may provide a crucial way to examine the underlying new physics.
