One-loop analysis of the four-Fermi contribution to the atomic EDM within RPVMSSM

Abstract

The contribution in the R-parity violating (RPV) Minimal Supersymmetric Standard Model (MSSM) to the electric dipole moment (EDM) of ${}^{199}$Hg at the one-loop level is evaluated. At the one-loop level, the ${}^{199}$Hg EDM receives RPV contribution whose couplings are of a different type from the tree level analysis. This contribution is shown to be constrained by using the limit to the CP-odd electron-nucleon (e-N) interaction given by the recent result of ${}^{199}$Hg EDM experiment.
