Impact of CMS Multi-jets and Missing Energy Search on CMSSM Fits

Abstract

Recent CMS data significantly extend the direct search exclusion for supersymmetry. We examine the impact of such data on global fits of the constrained minimal supersymmetric standard model (CMSSM) to indirect and cosmological data. By simulating supersymmetric signal events at the LHC, we construct a likelihood map for the recent CMS data, validating it against the exclusion region calculated by the experiment itself. A previous CMSSM global fit is then re-weighted by our likelihood map. The CMS results nibble away at the high fit probability density region, transforming probability distributions for the scalar and gluino masses. The CMS search has a non-trivial effect on tan beta due to correlations between the parameters implied by the fits to indirect data.

15 pages, 8 figures. v2 has an appendix added with further checks of A0-tan beta independence, expected sensitivity curves added to Fig 2a and typos fixed. v3 has extended discussion of re-weighting procedure and egregious points in the appendix. v4 minor changes due to very strict (but good) referee
