SUSY Higgs searches : beyond the MSSM

TL;DR

This paper explores how recent LHC Higgs search results constrain extended supersymmetric models beyond the MSSM, considering higher order operators and their effects on Higgs mass and decay modes.

Contribution

It recasts LHC Higgs search limits within a generic supersymmetric framework with higher order operators, extending beyond the MSSM and analyzing implications for Higgs properties.

Findings

Constraints on non-minimal SUSY models from LHC data

Potential increase in Higgs mass due to higher order operators

Impact of invisible Higgs decays on search strategies

Abstract

The recent results from the ATLAS and CMS collaborations show that the allowed range for a Standard Model Higgs boson is now restricted to a very thin region. Although those limits are presented exclusively in the framework of the SM, the searches themselves remain sensitive to other Higgs models. We recast the limits within a generic supersymmetric framework that goes beyond the usual minimal extension. Such a generic model can be parameterised through a supersymmetric effective Lagrangian with higher order operators appearing in the K\"ahler potential and the superpotential, an approach whose first motivation is to alleviate the fine-tuning problem in supersymmetry with the most dramatic consequence being a substantial increase in the mass of the lightest Higgs boson as compared to the minimal supersymmetic model. We investigate in this paper the constraints set by the LHC on such models. We also investigate how the present picture will change when gathering more luminosity. Issues of how to combine and exploit data from the LHC dedicated to searches for the standard model Higgs to such supersymmetry inspired scenarios are discussed. We also discuss the impact of invisible decays of the Higgs in such scenarios.
