Findings

Identifies allowed and excluded regions in sparticle mass planes.

Provides updated posterior distributions of pMSSM parameters.

Reveals broader phenomenological features compared to simplified models.

Abstract

The ATLAS collaboration published supersymmetry limits based on up to about 4.7 \ifb data collected over the year 2011 from LHC runs at 7 TeV. These were mainly interpreted within restricted, particular or simplified models for supersymmetry breaking schemes or scenarios. The pMSSM is an alternative and more generic supersymmetry framework which captures broader phenomenological features. Searching for more generic conclusions from the supersymmetry limits interpretation, we update a Bayesian global fit of the pMSSM to pre-LHC data using the LHC-7 limits. The posterior distributions show the most up to date features, revealing allowed versus excluded regions in sparticle mass planes within the MSSM.
