The supersymmetric Higgs boson with flavoured A-terms

TL;DR

This paper investigates how large flavour-violating A-terms in a supersymmetric model affect the Higgs boson properties, including mass and couplings, with implications for collider experiments.

Contribution

It provides explicit analytical formulas for the impact of flavour-violating A-terms on Higgs observables in supersymmetry, highlighting significant phenomenological effects.

Findings

Large flavour-violating A-terms significantly alter Higgs mass and couplings.

Explicit formulas reveal parametric dependencies of observables.

Implications for LHC and future collider searches are discussed.

Abstract

We consider a supersymmetric scenario with large flavour violating A-terms in the stop/scharm sector and study their impact on the Higgs mass, the electroweak rho parameter and the effective Higgs couplings to gluons, photons and charm quarks. For each observable we present explicit analytical expressions which exhibit the relevant parametric dependences, both in the general case and in specific limits. We find significant effects and comment on phenomenological implications for the LHC and future colliders.
