R-parity violating supersymmetric contributions to the P, CP-odd electron-nucleon interaction at the one-loop level

TL;DR

This paper calculates how R-parity violating supersymmetry affects the electron-nucleon interaction and atomic EDMs, providing tighter experimental constraints on certain RPV couplings and exploring implications for future experiments.

Contribution

It presents the first one-loop level calculation of RPV SUSY contributions to atomic EDMs and derives new constraints on RPV couplings from experimental data.

Findings

Current 199Hg EDM data constrains RPV couplings more tightly.

One-loop RPV interactions generate P, CP-odd 4-quark interactions.

Future experiments could further constrain RPV parameters.

Abstract

The contribution of the R-parity violating minimal supersymmetric Standard model (RPVMSSM) at the one-loop level to the 199Hg atomic electric dipole moment (EDM) through P, CP-odd electron-nucleon (e-N) interaction is calculated. We show that the current experimental data of the 199Hg EDM give tighter constraints on some of the imaginary parts of R-parity violating (RPV) coupling than those currently known. We add also the analysis of the P, CP-odd 4-quark interaction generated by R-parity violating interactions at the one-loop level, and discuss the possibility to constrain them in future experiments.
