Search for heavy quarks decaying into a top quark and a W or Z boson using lepton + jets events in pp collisions at √s = 7 TeV

S. Chatrchyan, +2345 more
- 24 Jan 2013 - 
TL;DR: In this paper, a search for the pair-production of heavy quarks, Q Q-bar, that decay exclusively into a top quark and a W or Z boson was performed using a sample of proton-proton collisions at 7 TeV corresponding to an integrated luminosity of 5.0 inverse femtobarns, collected by the Compact Muon Solenoid experiment.
Journal ArticleDOI

CMS Data Processing Workflows during an Extended Cosmic Ray Run

S. Chatrchyan, +2464 more
- 01 Dec 2010 - 
TL;DR: The Cosmic Run At Four Tesla (CMS) data taking exercise was held in 2008 as discussed by the authors, with the goal of commissioning the experiment for extended operation, with all installed detector systems participating.
Journal ArticleDOI

Search for Physics Beyond the Standard Model Using Multilepton Signatures in $pp$ Collisions at $s=7$ TeV

S. Chatrchyan, +2176 more
TL;DR: In this paper, a search for physics beyond the standard model in events with at least three leptons and any number of jets is presented, and the results constrain previously unexplored regions of supersymmetric parameter space.
Journal ArticleDOI

Measurement of the Z/γ*+b-jet cross section in pp collisions at √s = 7 TeV

S. Chatrchyan, +2320 more
- 01 Jan 2012 - 
TL;DR: In this article, the production of b jets in association with a Z/gamma* boson is studied using proton-proton collisions delivered by the LHC at a centre-of-mass energy of 7TeV and recorded by the CMS detector.
Journal ArticleDOI

Search for a W' boson decaying to a bottom quark and a top quark in pp collisions at s=7TeV

S. Chatrchyan, +2174 more
- 29 Jan 2013 - 
TL;DR: In this article, a search for a W′ boson using a dataset corresponding to 5.0 fb^(−1) of integrated luminosity collected during 2011 by the CMS experiment at the LHC in pp collisions at √s = 7Tev is presented.
