“…which constrains the parameter space of our model concretely [51]. We choose these parameters so that the corresponding theoretical prediction of the mass of the lightest CP-even Higgs fits the experimental data with 3 standard deviations: 124.37 GeV ≤ m h ≤ 125.81 GeV.…”

The double Higgs boson production through e þ e − → hhZ is analyzed in the minimal supersymmetric extension of the Standard Model (SM) with the local gauge symmetry Uð1Þ B−L , where h denotes the lightest Higgs boson with 125 GeV. Considering the constraints from the updated prediction data, we find that the production cross section of this process in the model depends on some parameters strongly.

In order to interpret the Higgs boson mass and its decays naturally, we hope to examine the BLMSSM and B-LSSM. In the both models, the right-handed neutrino superfields are introduced to better explain the neutrino mass problems. In this paper, we introduce the fine-tuning to acquire the physical Higgs boson mass. Besides, the method of $$\chi ^2$$ χ 2 analyses will be adopted in the BLMSSM and B-LSSM to fit the experimental data. Therefore, we can obtain the reasonable theoretical values of the Higgs decays and muon $$g-2$$ g - 2 that are in accordance with the experimental results respectively in the BLMSSM and B-LSSM.

“…The framework of the B-LSSM has been discussed detailedly in our previous works [106][107][108], which contain the particle content, the superpotential, the soft breaking terms, some mass matrices and interaction vertices. We do not introduce the model in detail in this work, but some relevant mass matrices will be given in section 2 for analyzing the numerical results clearly.…”

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.
