In the supersymmetric standard model (SSM) the $W$-boson could have a non-vanishing electric dipole moment (EDM) through a one-loop diagram mediated by the charginos and neutralinos. Then the $W$-boson EDM induces the EDMs of the neutron…

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…
