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 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

Search for gluino mediated bottom- and top-squark production in multijet final states in pp collisions at 8 TeV

S. Chatrchyan, +2225 more
- 01 Oct 2013 - 
TL;DR: In this article, a search for supersymmetry is presented based on events with large missing transverse energy, no isolated electron or muon, and at least three jets with one or more identified as a bottom-quark jet.
Journal ArticleDOI

Search for resonances in the dijet mass spectrum from 7 TeV pp collisions at CMS

S. Chatrchyan, +2229 more
- 13 Oct 2011 - 
TL;DR: In this article, a search for narrow resonances with a mass of at least 1 TeV in the dijet mass spectrum is performed using pp collisions at root s = 7 TeV corresponding to an integrated luminosity of 1 fb(-1), collected by the CMS experiment at the LHC.
