Suppressing supersymmetric flavor violations through quenched gaugino-flavor interactions

TL;DR

This paper proposes a mechanism to suppress flavor and CP violations in supersymmetry by quenching gaugino-flavor interactions through power-law running, leading to distinctive collider and dark matter detection signatures.

Contribution

It introduces a novel theoretical framework that disentangles SUSY couplings to suppress flavor violations and analyzes its implications for collider and dark matter experiments.

Findings

Suppressed flavor and CP violating SUSY couplings achieved.

Enhanced production of top, bottom, and tau at the LHC.

Dark matter detection signals may be more elusive.

Abstract

Realizing that couplings related by supersymmetry (SUSY) can be disentangled when SUSY is broken, it is suggested that unwanted flavor and CP violating SUSY couplings may be suppressed via quenched gaugino-flavor interactions, which may be accomplished by power-law running of sfermion anomalous dimensions. A simple theoretical framework to accomplish this is exemplified and the defeated constraints are tallied. One key implication of the scenario is the expectation of enhanced top, bottom and tau production at the LHC, accompanied by large missing energy. Also, direct detection signals of dark matter may be more challenging to find than in conventional SUSY scenarios.
