Search for new physics in the multijet and missing transverse momentum final state in proton-proton collisions at vs=7TeV

Abstract: A search for physics beyond the standard model is performed in events with at least three jets and large missing transverse momentum produced in proton-proton collisions at a center-of-mass energy of ffiffi s p ¼ 7 TeV. No significant excess of events above the expected backgrounds is observed in 4:98 fb1 of data collected with the CMS detector at the Large Hadron Collider. The results are presented in the context of the constrained minimal supersymmetric extension of the standard model and more generically for simplified models. For the simplified models of gluino-gluino and squark-squark production, gluino masses below 1.0 TeV and squark masses below 0.76 TeV are excluded in case the lightest supersymmetric particle mass is below 200 GeV. These results significantly extend previous searches.
