Search for supersymmetry in pp collisions at √s = 7 TeV in events with single lepton, jets, and missing transverse momentum


CMS Collaboration; Amsler, C; Chiochia, V; Snoek, H; Favaro, C; Verzetti, M; Schmitt, A; De Visscher, S; Otyugova, P; Ivova, M; Millan, B; Storey, J; Aguiló, E (2011). Search for supersymmetry in pp collisions at √s = 7 TeV in events with single lepton, jets, and missing transverse momentum. Journal of High Energy Physics, (8):156.

Abstract

Results are reported from a search for physics beyond the standard model in proton-proton collisions at a center-of-mass energy of 7 TeV, focusing on the signature with a single, isolated, high-transverse-momentum lepton (electron or muon), energetic jets, and large missing transverse momentum. The data sample comprises an integrated luminosity of 36 inverse picobarns, recorded by the CMS experiment at the LHC. The search is motivated by models of new physics, including supersymmetry. The observed event yields are consistent with standard model backgrounds predicted using control samples obtained from the data. The characteristics of the event sample are consistent with those expected for the production of t t-bar and W +jets events. The results are interpreted in terms of limits on the parameter space for the constrained minimal supersymmetric extension of the standard model.
