Contribution

It provides a detailed analysis of one-loop diagrams contributing to quark EDMs in the BLMSSM, considering CP-violating phases and exploring parameter space effects.

Findings

c and t EDMs can reach large values

New CP-violating sources significantly impact EDM predictions

Numerical results depend on parameter assumptions

Abstract

In the CP violating supersymmetric extension of the standard model with local gauged baryon and lepton symmetries(BLMSSM), there are new CP violating sources which can give new contributions to the quark electric dipole moment (EDM). Considering the CP violating phases, we analyze the EDMs of the quarks c and t. We take into account the contributions from the one loop diagrams. The numerical results are analyzed with some assumptions on the relevant parameter space. The numerical results for the c and t EDMs can reach large values.
