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 U(1) X SSM is the extension of the minimal supersymmetric standard model (MSSM) and its local gauge group is SU(3) C × SU(2) L × U(1) Y × U(1) X . To obtain this model, three singlet new Higgs superfields and right-handed neutrinos are ad

As the U(1) extension of the minimal supersymmetric standard model, the U(1)XSSM has new superfields, such as right-handed neutrinos, and three Higgs singlets. In the U(1)XSSM, the lightest CP-even Higgs mass mh0 is studied by using the Higgs effecti

The U(1)X extension of the minimal supersymmetric standard model (MSSM) is called as U(1)XSSM with the local gauge group SU(3)C×SU(2)L×U(1)Y×U(1)X. U(1)XSSM has three singlet Higgs superfields beyond MSSM. In U(1)XSSM, the mass matrix of neutralin

We present an approach to analyze the scalar integrals of any Feynman diagrams in detail here. This method not only completely recovers some well-known results in the literature, but also produces some new results on the C0 function. The approach can

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

Basing on the systems of linear partial differential equations derived from Mellin-Barnes representations and Miller's transformation, we obtain GKZ-hypergeometric systems of one-loop self energy, one-loop triangle, two-loop vacuum, and two-loop suns

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

Abstract To extend the BLMSSM, we not only add exotic Higgs superfields $$(\Phi _{NL},\varphi _{NL})$$ (ΦNL,φNL) to make the exotic lepton heavy, but also introduce the superfields (Y,$$Y^\prime $$ Y′ ) having couplings with lepton and exotic lep
