Phenomenological MSSM in light of new 13 TeV LHC data

TL;DR

This paper analyzes the phenomenological MSSM with neutralino dark matter using new 13 TeV LHC data, deriving exclusion bounds and updating the allowed parameter space based on recent experimental searches.

Contribution

First analysis of p19MSSM with neutralino dark matter incorporating 13 TeV LHC data, recasting multiple ATLAS analyses to set new exclusion bounds.

Findings

25% of model points excluded at 95% C.L.

Allowed spectrum includes stops >400 GeV, gluinos >790 GeV, squarks >440 GeV.

Updated constraints significantly restrict the parameter space.

Abstract

We present the first analysis of the p19MSSM with neutralino dark matter, in light of 13 TeV LHC data with an integrated luminosity of ~14/fb. We recast twelve experimental analyses performed by the ATLAS collaboration and derive exclusion bounds on the parameter space of the model. We find that 25% of the model points can be excluded at 95% C.L. by a combination of the implemented searches. The spectrum allowed after the 13 TeV results are taken into account presents stops heavier than at least 400 GeV, gluinos heavier than at least 790 GeV, and squarks of the first and second generation heavier than at least 440 GeV.
