Abstract:
We interpret within the phenomenological MSSM (pMSSM) results from searches for new physics performed by CMS in pppp data sets collected at 7~TeV and 8~TeV, corresponding to integrated luminosities of 5~fb1^{-1} and 19.5~fb1^{-1}, respectively. The pMSSM is a 19-parameter realization 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 than , and complimentary to, 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.
