“…Based on our previous analyses on the muon anomalous MDM [109][110][111][112][113][114], the Higgs boson mass, the Higgs boson decays andB → X s γ in the B-LSSM, the muon anomalous MDM depends on M E , µ, tan β; the Higgs boson mass depends on A t , Mt, tan β; the Higgs boson decay modes h → gg, ZZ, W W, bb, ττ depend on A t , A b , µ, Mt, Mb, tan β, M H ± (charged Higgs boson mass), the B meson rare decay processB → X s γ depends on M H ± , A t , Mt, tan β. In addition, the new parameters g B , g Y B , tan β can affect contributions to all these measured quantities.…”

The difference between the updated experimental result on the muon anomalous magnetic dipole moment and the corresponding theoretical prediction of the standard model on that is about 4.2 standard deviations. In this work, we calculate the muon anomalous MDM at the two-loop level in the supersymmetric B − L extension of the standard model. Considering the experimental constraints on the lightest Higgs boson mass, Higgs boson decay modes h → γγ, WW, ZZ, $$ b\overline{b} $$ b b ¯ , $$ \tau \overline{\tau} $$ τ τ ¯ , B rare decay $$ \overline{B} $$ B ¯ → Xsγ, and the transition magnetic moments of Majorana neutrinos, we analyze the theoretical predictions of the muon anomalous magnetic dipole moment in the B − L supersymmetric model. The numerical analyses indicate that the tension between the experimental measurement and the standard model prediction is remedied in the B − L supersymmetric model.

“…Refs. [109][110][111][112][113][114] show that the theoretical predictions of the muon anomalous MDM and the transition magnetic moments of Majorana neutrinos in the B-LSSM depend on sleptons, neutralinos and charginos strongly. On the basis (ẽ L ,ẽ R ), the mass matrix of charged sleptons is given as:…”

Recently, the CMS and ATLAS collaborations have reported direct searches for the 125 GeV Higgs decay with lepton flavor violation, h → μτ. In this work, we analyze the signal of the lepton flavour violating (LFV) Higgs decay h → μτ in the μ from ν Supersymmetric Standard Model (μνSSM) with slepton flavor mixing. Simultaneously, we consider the constraints from the LFV decay τ → μγ, the muon anomalous magnetic dipole moment and the lightest Higgs mass around 125 GeV.

Recently, the Muon g-2 experiment at Fermilab has measured the muon anomalous magnetic dipole moment (MDM), $a_\mu=(g_\mu-2)/2$, which reported that the new experimental average increases the tension between experiment and the standard model (SM) prediction to 4.2$\sigma$. In this work, we reanalyse the muon anomalous MDM at two-loop level in the $\mu$ from $\nu$ Supersymmetric Standard Model ($\mu\nu$SSM) combined with the updated experimental average. The $\mu\nu$SSM can explain the current tension 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 $\bar{B}\rightarrow X_s\gamma$ 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 two-loop level in the $\mu\nu$SSM. In addition, the 125 GeV Higgs boson decays to a pair of charged leptons in the $\mu\nu$SSM are also analysed.
