| contents | The N-B-LSSM is an extension of the minimal supersymmetric standard model (MSSM) with the addition of three singlet new Higgs superfields and right-handed neutrinos, whose local gauge group is $SU(3)_C\times SU(2)_L\times U(1)_Y\times U(1)_{B-L}$. In the N-B-LSSM, we study lepton flavor violating decays $l_j\rightarrow l_iγ$, $l_j \rightarrow 3l_i$ and $μ\rightarrow e+ q\bar q$ $(j=τ,μ,~i=μ,e$ and $i\neq j)$. Based on the current experimental limitations, we carry out detailed parameter scanning and numerical calculations to analyse the effects of different sensitive parameters on lepton flavor violation (LFV) in the N-B-LSSM. The numerical results show that the non-diagonal elements involving the initial and final leptons are main sensitive parameters and LFV sources. This work can provide a strong basis for exploring new physics (NP) beyond the Standard Model (SM). |
