Journal ArticleDOI

Search for physics beyond the standard model in events with τ leptons, jets, and large transverse momentum imbalance in pp collisions at s√ = 7 TeV

S. Chatrchyan, +3928 more
- 01 Jul 2013 - 
TL;DR: In this article, a search for physics beyond the standard model was performed with events having one or more hadronically decaying τ leptons, highly energetic jets, and large transverse momentum imbalance.
Journal ArticleDOI

Observation of top quark pairs produced in association with a vector boson in pp collisions at $\sqrt{s} =$ 8 TeV

Vardan Khachatryan, +2374 more
- 18 Jan 2016 - 
TL;DR: In this paper, the cross sections for top quark pairs produced in association with a W or Z boson are presented, using 8 TeV pp collision data corresponding to an integrated luminosity of 19.5 fb^(−1).
Journal ArticleDOI

Search for supersymmetry in pp collisions at √s=7 TeV in events with two photons and missing transverse energy

S. Chatrchyan, +2203 more
- 24 May 2011 - 
TL;DR: Upper limits on the signal cross section for general gauge-mediated supersymmetry between 0.3 and 1.1 pb at the 95% confidence level are determined for a range of squark, gluino, and neutralino masses, excluding supersymmetric parameter space that was inaccessible to previous experiments.
Journal ArticleDOI

Measurement of the relative prompt production rate of χc2 and χc1 in pp collisions at √s = 7 TeV

S. Chatrchyan, +3918 more
- 01 Jan 2012 - 
TL;DR: A measurement is presented of the relative prompt production rate of χc2 and φ with 4.6 fb−1 of data collected by the CMS experiment at the LHC in pp collisions at $\sqrt{s}= 7~\mathrm{TeV}$.
Journal ArticleDOI

Measurement of dijet angular distributions and search for quark compositeness in pp collisions at √s=7TeV

Vardan Khachatryan, +2213 more
- 18 May 2011 - 
TL;DR: Dijet angular distributions are measured over a wide range of dijet invariant masses in pp collisions at √s = 7 TeV, at the CERN LHC, and are found to be in good agreement with the predictions of perturbative QCD, and yield no evidence of quark compositeness.
