\begin{document}$ U(1)_X $\end{document}SSM, whose local gauge group is \begin{document}$S U(3)_C \times S U(2)_L \times U(1)_Y \times U(1)_X$\end{document}. To obtain the \begin{document}$ U(1)_X $\end{document}SSM, we add new superfields to the MSSM, namely, three Higgs singlets \begin{document}$ \hat{\eta},\; \hat{\bar{\eta}},\; \hat{S} $\end{document} and right-handed neutrinos \begin{document}$ \hat{\nu}_i $\end{document}. The charge conjugate and parity (CP) violating effects are considered to study the lepton electric dipole moment (EDM) in the \begin{document}$ U(1)_X $\end{document}SSM. There are more CP violating phases in the \begin{document}$ U(1)_X $\end{document}SSM than in the standard model (SM). In this model, several new parameters \begin{document}$ (\theta_S, \theta_{BB^{\prime}}, \theta_{BL}) $\end{document} 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."> Study of lepton EDMs in the <i>U</i>(1)<sub><i>X</i></sub> SSM -
