A Complete Analysis of "Flavored" Electric Dipole Moments in Supersymmetric Theories

TL;DR

This paper systematically evaluates electric dipole moments in supersymmetric theories, highlighting the dominance of beyond-leading-order effects over leading-order contributions in large parameter regions, which is crucial for accurate predictions.

Contribution

It provides a comprehensive analysis of BLO contributions to EDMs in SUSY models, demonstrating their importance over LO effects in flavor-violating scenarios.

Findings

BLO effects often dominate over LO in EDM predictions.

Inclusion of BLO effects is essential for accurate SUSY EDM evaluations.

Relevance of BLO effects shown in SUSY SU(5) model with right-handed neutrinos.

Abstract

The Standard Model predictions for the hadronic and leptonic electric dipole moments (EDMs) are well far from the present experimental resolutions, thus, the EDMs represent very clean probes of New Physics effects. Especially, within supersymmetric frameworks with flavor-violating soft terms large and potentially visible effects to the EDMs are typically expected. In this work, we systematically evaluate the predictions for the EDMs at the beyond-leading-order (BLO). In fact, we show that BLO contributions to the EDMs dominate over the leading-order (LO) effects in large regions of the supersymmetric parameter space. Hence, their inclusion in the evaluation of the EDMs is unavoidable. As an example, we show the relevance of BLO effects to the EDMs for a SUSY $SU(5)$ model with right-handed neutrinos.
