Phenomenological MSSM interpretation of the CMS 7 and 8 TeV results — •Lukas Vanelderen, Christian Sander, and Teresa Lenz — University of Hamburg, Germany

We interpret within the phenomenological MSSM (pMSSM) results from searches for new physics performed by CMS in pp data sets collected at 7 TeV and 8 TeV, corresponding to integrated luminosities of 5 fb⁻¹ and 19.5 fb⁻¹, respectively. The pMSSM is a 19-parameter realisation of the MSSM, defined at the SUSY scale, that captures most of the features of the general R-parity conserving weak-scale MSSM. It allows us to draw conclusions that are more generic, and therefore more robust, than those derived in more constrained models, including simplified models and those that impose particular SUSY breaking schemes, such as the CMSSM. We perform a global Bayesian analysis on a data set, which in addition to CMS search results, includes data from pre-CMS and indirect measurements. We study posterior probability densities of model parameters, masses and observables and study implications for the MSSM Higgs sector and dark matter searches. Our study provides a coherent global picture of how the current CMS searches constrain supersymmetry in general.
