Measurement of the lepton charge asymmetry in inclusive W production in pp collisions at √s=7 TeV

S. Chatrchyan, +2236 more
- 01 Apr 2011 - 
TL;DR: In this article, a measurement of the lepton charge asymmetry in WX production at 7 TeV was presented based on data recorded by the CMS detector at the LHC and corresponding to an integrated luminosity of 36 inverse picobarns.
Journal ArticleDOI

Combined search for electroweak production of charginos and neutralinos in proton-proton collisions at √s=13 TeV

Albert M. Sirunyan, +2317 more
- 27 Mar 2018 - 
TL;DR: A statistical combination of several searches for the electroweak production of charginos and neutralinos is presented in this article, where a targeted analysis requiring three or more charged leptons (electrons or muons) is presented, focusing on the challenging scenario in which the difference in mass between the two least massive neutralino is approximately equal to the mass of the Z boson.
Journal ArticleDOI

Evidence for transverse-momentum- and pseudorapidity-dependent event-plane fluctuations in PbPb and pPb collisions

Vardan Khachatryan, +2262 more
- 22 Sep 2015 - 
TL;DR: In this article, a systematic study of the factorization of long-range azimuthal twoparticle correlations into a product of single-particle anisotropies is presented as a function of pT and nu of both particles.
Journal ArticleDOI

Performance of τ-lepton reconstruction and identification in CMS

S. Chatrchyan, +2288 more
- 01 Jan 2012 - 
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.
Journal ArticleDOI

Measurement of the inelastic proton-proton cross section at s√=7 TeV

S. Chatrchyan, +2195 more
- 13 May 2013 - 
TL;DR: In this paper, a measurement of the inelastic proton-proton cross section at a center-of-mass energy of 7 TeV was presented using the CMS detector at the LHC.
