| 英文摘要 | The theoretical predictions in the standard model (SM) and measurements on the anomalous magnetic dipole moments (MDM) of muons and electrons have great precision, hence the MDMs of muon and electron have close relation with the new physics (NP) beyond the SM. Recently, a negative similar to 2.4 sigma discrepancy between the measured electron MDM and the SM prediction results from a recent improved determination of the fine structure constant. Combined with the long-lasting muon MDM discrepancy which is about similar to 3.7 sigma, it is difficult to explain both the magnitude and opposite signs of the deviations in a consistent model, without introducing large flavor-violating effects. The analysis shows that they can be explained in the minimal supersymmetric extension (MSSM) of the SM with local B - L gauge symmetry (B-LSSM). Comparing with the MSSM, new parameters in the B-LSSM can affect the theoretical predictions on lepton MDMs, and the effects of them are explored. |
