| contents | It is well known that the muon magnetic dipole moment (MDM) has close relation with the new physics (NP) in the development of the Standard Model (SM). Combined with the Fermilab National Accelerator Laboratory (FNAL) and the Brookhaven National Laboratory (BNL) E821 result, the departure from the SM prediction is about 5.0 $σ$. We study the electroweak corrections from several type two-loop SUSY diagrams and the virtual SUSY particles include chargino, neutralino, scalar lepton and scalar neutrino. Based on the latest experimental constraints, we study the {muon anomalous MDM} under the next to the minimal supersymmetric extension of the SM with local B-L gauge symmetry (N-B-LSSM). The abundant numerical results verify that $\tanβ,~T_e,~M^2_L,~M^2_e,~M_{BB'}$ play an important role in {muon anomalous MDM}. $M^2_e,~\tanβ$ and $T_e$ are sensitive parameters to {muon anomalous MDM}. From the data obtained in all the figures of the numerical results, most of the values of $a_μ^{NBL}$ are in 2$σ$ interval, which can compensate the departure between the experiment data and the SM prediction. |
