An update of the constraints on the phenomenological MSSM from the new LHC Higgs results

TL;DR

This paper updates constraints on the phenomenological MSSM using recent LHC Higgs results, rare decay observations, and dark matter detection limits, refining the model's parameter space with new experimental data.

Contribution

It provides an extended analysis of the pMSSM parameter space incorporating the latest experimental constraints from LHC, LHCb, and XENON experiments.

Findings

Stronger constraints on pMSSM parameters from Higgs decay data.

New limits from B_s -> mu+mu- decay observations.

Refined parameter space considering dark matter detection results.

Abstract

Updated results on the search of Higgs bosons at the LHC with up to 17/fb of data have just been presented by the ATLAS and CMS collaborations. New constraints are provided by the LHCb and XENON experiments with the observation of the rare decay B_s -> mu+mu- and new limits on dark matter direct detection. In this paper, we update and extend the results on the implications of these data on the phenomenological Minimal Supersymmetric extension of the Standard Model (pMSSM) by using high statistics, flat scans of its 19 parameters. The new LHC data on bb and tau tau decays of the lightest Higgs state and the new CMS limits from the tau tau searches for the heavier Higgs states set stronger constraints on the pMSSM parameter space.
