Determination of jet energy calibration and transverse momentum resolution in CMS

S. Chatrchyan, +2271 more
TL;DR: In this article, the transverse momentum balance in dijet and γ/Z+jets events is used to measure the jet energy response in the CMS detector, as well as the transversal momentum resolution.
Journal ArticleDOI

Search for supersymmetry at the LHC in events with jets and missing transverse energy

S. Chatrchyan, +2295 more
TL;DR: In this paper, a search for events with jets and missing transverse energy is performed in a data sample of pp collisions collected at 7 TeV by the CMS experiment at the LHC.
Journal ArticleDOI

Search for invisible decays of Higgs bosons in the vector boson fusion and associated ZH production modes

S. Chatrchyan, +2233 more
TL;DR: The observed (expected) upper limit on the invisible branching fraction at 0.58 (0.44) is interpreted in terms of a Higgs-portal model of dark matter interactions.
Journal ArticleDOI

Measurement of the inclusive W and Z production cross sections in pp collisions at √s = 7 TeV with the CMS experiment

S. Chatrchyan, +2250 more
TL;DR: In this paper, a measurement of W and Z production cross sections in pp collisions at 7 TeV is presented, where electron and muon decay channels are analyzed in a data sample collected with the CMS detector at the LHC and corresponding to an integrated luminosity of 36 inverse picobarns.
Journal ArticleDOI

Performance of τ-lepton reconstruction and identification in CMS

S. Chatrchyan, +2288 more
TL;DR: In this paper, the performance of tau-lepton reconstruction and identification algorithms was studied using a data sample of proton-proton collisions at 7 TeV, corresponding to an integrated luminosity of 36 inverse picobarns collected with the CMS detector at the LHC.
