| contents | In the framework of the minimal supersymmetric model extension with new scalar triplets and singlet (TNMSSM), we analyze the electric dipole moment (EDM) of neutron ($d_n$), electron EDM($d_e$), the mercury EDM($d_{Hg}$), $b$ quark ($d_b$) and $c$ quark ($d_c$) by considering the contributions from the one-loop diagrams, some two-loop diagrams and the Weinberg operators. The effects of TNMSSM specific CPV sources $χ_d,\;χ_t$ on $d_n$, $d_e$, $d_{Hg}$, $d_b$, $d_c$ are specialized, it is found that they have significant contributions to these EDMs, and the current upper bounds on $d_n$ impose strict constraints on $χ_d,\;χ_t$. The theoretical predictions on $d_b$, $d_c$ can reach about $10^{-22}$ e$\cdot$cm and $10^{-23}$ e$\cdot$cm respectively by taking the upper bounds on $d_n$, $d_e$, $d_{Hg}$ into account, which have great potential to be observed in future. |
