Abstract A flavor-dependent model (FDM) is proposed in this work. The model extends the Standard Model by an extra $$U(1)_F$$ U ( 1 ) F local gauge group, two scalar doublets, one scalar singlet and two right-handed neutrinos, where the additional $$

Abstract The B-L symmetric SUSY model (B-LSSM) introduces a new $$Z'$$ Z ′ gauge boson and two singlet scalars, which indicates there are more neutralinos in the B-LSSM comparing with the minimal SUSY extension of standard model (MSSM). These new n

Abstract Applying the system of linear partial differential equations derived from the Mellin–Barnes representation and the Miller transformation, we present the GKZ-system of the Feynman integral of the 2-loop self energy diagram with 4 propagator

Abstract The MSSM is extended to the $$U(1)_X$$ U ( 1 ) X SSM, whose local gauge group is $$SU(3)_C \times SU(2)_L \times U(1)_Y \times U(1)_X$$ S U ( 3 ) C × S U ( 2 ) L × U ( 1 ) Y × U ( 1 ) X . To obtain the $$U(1)_X$$ U ( 1 ) X SSM, we add the

Abstract 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 pap

Abstract The experimental data of the magnetic dipole moment(MDM) of lepton(e, $$\mu $$ μ ) is very exact. The deviation between the experimental data and the standard model prediction maybe come from new physics contribution. In the supersymmetric

Abstract Electroweak baryogenesis (EWB) and electric dipole moment (EDM) have close relation with the new physics beyond the standard model (SM), because the SM CP-violating (CPV) interactions are not sufficient to provide the baryon asymmetry of the

Abstract Within the extended BLMSSM, the exotic Higgs superfields $$(\Phi _{NL},\varphi _{NL})$$ (ΦNL,φNL) are added to make the exotic leptons heavy, and the superfields ($$Y,Y^\prime $$ Y,Y′ ) are also introduced to make exotic leptons unstable

Abstract The rare decays $$\bar{B}\rightarrow X_s\gamma $$ B¯→Xsγ and $$B_s^0\rightarrow \mu ^+\mu ^-$$ Bs0→μ+μ- are important to research new physics beyond the standard model (SM). In this work, we investigate two loop electroweak correctio

Abstract The decays of top quark $$t\rightarrow c\gamma ,\;t\rightarrow cg,\;t\rightarrow cZ,\;t\rightarrow ch$$ t→cγ,t→cg,t→cZ,t→ch are extremely rare processes in the standard model (SM). The predictions on the corresponding branching rati
