Constraints on the MSSM from the Higgs Sector - A pMSSM Study of Higgs Searches, Bs -> mu+ mu- and Dark Matter Direct Detection

TL;DR

This study evaluates how LHC Higgs searches, B meson decays, and dark matter experiments constrain the MSSM parameter space, especially focusing on Higgs mass ranges around 125 GeV and their impact on SUSY models.

Contribution

It provides a comprehensive analysis of MSSM constraints from multiple experimental avenues, highlighting the broader coverage of Higgs sector constraints over traditional SUSY searches.

Findings

Higgs sector constraints cover a larger SUSY parameter space than strongly interacting particle searches.

A Higgs mass around 125 GeV significantly restricts MSSM scenarios.

Non-observation of the lightest Higgs further constrains MSSM models.

Abstract

We discuss the constraints on Supersymmetry in the Higgs sector arising from LHC searches, rare B decays and dark matter direct detection experiments. We show that constraints derived on the mass of the lightest h0 and the CP-odd A0 bosons from these searches are covering a broader fraction of the SUSY parameter space compared to searches for strongly interacting supersymmetric particle partners. We discuss the implications of a mass determination in the range 123 < Mh < 127 GeV, inspired by the intriguing hints reported by the ATLAS and CMS collaborations, as well as those of a non-observation of the lightest Higgs boson on MSSM scenarios not excluded at the end of 2012 by LHC and direct dark matter searches and their implications on LHC SUSY searches.
