Abstract

Abstract U(1)XSSM is the extension of the minimal supersymmetric standard model (MSSM) and its local gauge group is SU(3)C × SU(2)L × U(1)Y × U(1)X. To obtain this model, three singlet new Higgs superfields and right-handed neutrinos are added to MSSM. In the framework of U(1)XSSM, we study lepton flavor violating decays τ → Pl( P = π, η, η′; l = μ, e). According to the latest experimental data of τ → Pe and τ → Pμ, the influence of different sensitive parameters on the results is analyzed to make a reasonable prediction for future experiments. From the numerical analysis, the non-diagonal elements which correspond to the generations of the initial lepton and final lepton are main sensitive parameters and lepton flavor violation (LFV) sources. This work can provide a basis for finding the existence of new physics (NP).
