Kurzfassung

We have investigated the implications for the constrained minimal supersymmetric model (CMSSM) from the absence of any signal in the first period of LHC data taking at 7 TeV center-of-mass energy with 2 fb−1 integrated luminosity. We have considered the zero-lepton plus four jets and missing transverse energy signature, and performed a combined fit of low-energy measurements, the dark matter relic density constraint and LHC exclusions. The non-observation of supersymmetry in the first period of LHC data taking stills allow for a reasonable description of low-energy data and the dark matter relic density even within the CMSSM, but excludes squarks and gluinos with masses below 1 TeV.
