Higgs coupling measurements and impact on the MSSM

TL;DR

This paper reviews how Higgs boson measurements from LHC Run I constrain the parameter space of the MSSM, especially considering the implications for supersymmetric models with dark matter candidates.

Contribution

It provides a comprehensive analysis of Higgs data constraints on the MSSM, including scenarios with a light neutralino dark matter candidate.

Findings

Higgs measurements significantly restrict MSSM parameters.

Constraints on supersymmetric particles are derived from Higgs data.

Implications for dark matter models within MSSM are discussed.

Abstract

Run I of the LHC has not revealed any sign of new physics beyond the Standard Model (BSM). However, the discovery of an SM-like Higgs boson with mass around 125 GeV opens up new possibilities for probing various BSM scenarios with enlarged Higgs sectors and/or new particles affecting the loop-induced processes or opening new decay modes. We will present how we derive constraints on new physics from the Higgs measurements performed by the ATLAS and CMS collaborations. The impact of these measurements will then be assessed in the context of the general phenomenological Minimal Supersymmetric Standard Model (MSSM) and in the MSSM with a light neutralino as a dark matter candidate.
