Flavor violation in the MSSM and implications for top and squark searches at colliders

TL;DR

This paper explores how flavor physics constraints in the MSSM influence collider signatures, particularly through right-handed currents affecting top production and squark mass splittings impacting decay chains.

Contribution

It provides a detailed analysis of flavor-physics-induced effects in the MSSM relevant for collider experiments, highlighting new potential signals and constraints.

Findings

Right-handed W-couplings can enhance single-top production at the LHC.

Mass splittings between left-handed squarks are constrained by Kaon and D mixing.

Implications for squark decay chains at colliders are discussed.

Abstract

In this article I review some connections between flavor physics and collider physics. The first part discusses the effect of right-handed charged currents on the determination of the CKM elements V_ub. It is shown that such an effective right-handed W-coupling can be generated in the MSSM which would lead to a sizable enhancement of single-top production at the LHC. The second part of this article focuses on the constraints on the mass splitting between left-handed squarks from Kaon and D mixing. Such a mass splitting has interesting consequences for squark decay chains at colliders.
