| 英文摘要 | Recently, the Muon g-2 experiment at Fermilab measured the muon anomalous magnetic dipole moment (MDM), a(mu) = (g(mu)-2)/2, and reported that the new experimental average increases the difference between the experiment and the standard model (SM) prediction to 4.2 sigma. In this work, we reanalyze the muon anomalous MDM at the two-loop level in the mu from the nu Supersymmetric Standard Model (mu nu SSM) combined with the updated experimental average. The mu nu SSM can explain the current difference between the experimental measurement and the SM theoretical prediction for the muon anomalous MDM, constrained by the 125 GeV Higgs boson mass and decays, the rare decay (B) over bar -> X-s gamma, and so on. We also investigate the anomalous MDM of the electron and tau lepton, a(e) = (g(e) -2)/2 and a(tau) = (g(tau)-2)/2, at the two-loop level in the mu nu SSM. In addition, the decaying of the 125 GeV Higgs boson into a pair of charged leptons in the mu nu SSM is analyzed. |
