Abstract

In this paper, we study the lepton flavor violating decays of the ljliγγl_j\rightarrow l_i \gamma\gamma (j=2, 3; i=1, 2) processes under the U(1)XU(1)_XSSM. The U(1)XU(1)_XSSM is the addition of three singlet new Higgs superfields and right-handed neutrinos to the minimal supersymmetric standard model (MSSM). Based on the latest experimental constraints of ljliγγl_j\rightarrow l_i \gamma\gamma, we analyze the effects of different sensitive parameters on the results and made reasonable predictions for future experimental development. Numerical analysis shows that many parameters have a greater or lesser effect on lepton flavor violation(LFV), but the main sensitive parameters and sources leading to LFV are the non-diagonal elements involving the initial and final leptons. This work could provide a basis for the discovery of the existence of new physics (NP).
