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 ρ 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.
Highlights
The recent discovery of a Higgs particle at the LHC [1] has confirmed the validity of the Standard Model (SM)
The framework beyond the SM that we have examined in this paper is a SUSY scenario with large flavour violating A-terms in the stop/scharm sector
By integrating out stop and scharm squarks at the one-loop level, we have computed the leading corrections induced by Atc and Act on the Higgs mass, the electroweak ρ parameter and the effective Higgs couplings to gluons, photons and charm quarks
Summary
The recent discovery of a Higgs particle at the LHC [1] has confirmed the validity of the Standard Model (SM). Our aim is to investigate some properties of such SM-like Higgs field in a particular region of the SUSY parameter space, characterized by large values of certain flavour violating trilinear couplings. We do not specify either a flavour model or a mechanism of SUSY breaking, treat Atc and Act as phenomenological parameters (on the same footing as Xt) and allow them to be as large as the flavour conserving stop and scharm masses. Even in the latter limit the constraints from flavour changing observables are weak or absent, especially for O(TeV) squark masses. The dependence on trilinear parameters will appear through powers of Xt/m , Atc/m , Act/m
