Summary: | Abstract
The minimal supersymmetric extension of the standard model (MSSM) is extended to the
SSM, whose local gauge group is
. To obtain the
SSM, we add new superfields to the MSSM, namely, three Higgs singlets
and right-handed neutrinos
. The charge conjugate and parity (
CP)
violating effects are considered to study the lepton electric dipole moment (EDM) in the
SSM. There are more
CP
violating phases in the
SSM than in the standard model (SM). In this model, several new parameters
are considered as
CP
violating phases; hence, there are new contributions to lepton EDMs. This is conducive to exploring the source of
CP
violation and probing new physics beyond the SM. |
