英文摘要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 universe by many orders of magnitude, and the theoretical predictions for the EDM of electron (de) in the SM are too tiny to be detected in near future. In this work, we explore the CPV effects on EWB and the electron EDMin the minimal supersymmetric extension (MSSM) of the SM with local B - L gauge symmetry (B-LSSM). And the two-step transition via tree-effects in this model is discussed. Including two-loop corrections to de and considering the constrains from updated experimental data, the numerical results show that the B-LSSM can account for the observed baryon asymmetry. In addition, when the cancellation between different contributions to de takes place, the region favored by EWB can be compatible with the corresponding EDM bound.
