Lepton-flavor violation and (g−2)μ in the μνSSM

Within framework of thefrom ν Supersymmetric Standard Model (�νSSM), exotic singlet right-handed neutrino superfields induce new sources for lepton- flavor violation. In this work, we investigate some lepton-flavor violating processes in detail in the �νSSM. The numerical results indicate that the branching ratios for lepton-flavor violating processes � → eγ, τ → �γ and � → 3e can reach 10 −12 when tanβ is large enough, which can be detected in near future. We also discuss the constraint on the relevant parameter space of the model from the muon anomalous magnetic dipole moment. In addition, from the scalars for the �νSSM we strictly separate the Goldstone bosons, which disappear in the physical gauge.

Gauged baryon and lepton numbers in supersymmetry with a 125 GeV Higgs

Abstract Assuming that the Yukawa couplings between the Higgs and exotic quarks cannot be ignored, we analyze the signals of decay channels h → γ γ and h → V V ⁎ ( V = Z , W ) with the Higgs mass around 125 GeV in a supersymmetric extension of the standard model where baryon and lepton numbers are local gauge symmetries. Adopting some assumptions on relevant parameter space, we can account for the experimental data on Higgs from ATLAS and CMS naturally.

Neutron electric dipole moment in CP violating BLMSSM

A bstractConsidering the CP violating phases, we analyze the neutron electric dipole moment (EDM) in a CP violating supersymmetric extension of the standard model where baryon and lepton numbers are local gauge symmetries(BLMSSM). The contributions from the one loop diagrams and the Weinberg operators are taken into account. Adopting some assumptions on the relevant parameter space, we give the numerical results analysis. The numerical results for the neutron EDM can reach 1.05 × 10−25(e.cm), which is about the experimental upper limit.

Muon conversion to electron in nuclei within the μνSSM with a 125 GeV Higgs

A bstractWithin framework of the μ from ν Supersymmetric Standard Model (μνSSM), three exotic right-handed neutrino superfields induce new sources for lepton-flavor violation. In this work, we investigate muon conversion to electron in nuclei within the μνSSM in detail. With a 125GeV Higgs, the numerical results indicate that the μ − e conversion rates in nuclei within the μνSSM can reach the experimental upper bound, which could be detected with the future experimental sensitivities.

125 GeV Higgs boson decays in the μ from ν supersymmetric standard model

Recently the ATLAS and CMS Collaborations have reported significant events that are attributed to the neutral Higgs boson with mass around 125 GeV. In this work, we investigate the signals of the Higgs boson decay channels
