Search for lepton flavor violation in supersymmetric models via meson decays

Abstract

Considering the constraints from the experimental data on $\mu\rightarrow e\gamma$, $\mu\rightarrow3e$, $\mu-e$ conversion etc., we analyze the Lepton Flavor Violating decays $\phi(J/\Psi,\Upsilon(1S)) \rightarrow e^+\mu^-(\mu^+\tau^-)$ in the scenarios of the minimal supersymmetric extensions of Standard Model with seesaw Mechanism. Numerically, there is parameter space that the LFV processes of $J/\Psi(\Upsilon)\rightarrow\mu^+\tau^-$ can reach the upper experimental bounds, meanwhile the theoretical predictions on $\mu\rightarrow e\gamma$, $\mu\rightarrow3e$, $\mu-e$ conversion satisfy the present experimental bounds. For searching of new physics, Lepton Flavor Violating processes $J/\Psi(\Upsilon)\rightarrow\mu^+\tau^-$ may be more promising and effective channels.
