Measurement of the $t \bar{t}$ production cross section in the dilepton channel in pp collisions at $\sqrt{s}$ = 8 TeV

S. Chatrchyan, +2207 more
- 29 Dec 2013 - 
TL;DR: The top-antitop quark (t t-bar) production cross section is measured in proton-proton collisions at 8 TeV with the CMS experiment at the LHC, using a data sample corresponding to an integrated luminosity of 5.3 inverse femtobarns as discussed by the authors.
Journal ArticleDOI

Search for neutral Higgs bosons decaying to tau pairs in pp collisions at √s = 7 TeV

S. Chatrchyan, +2247 more
TL;DR: In this paper, a search for neutral Higgs bosons decaying to tau pairs at a center-of-mass energy of 7 TeV is performed using a dataset corresponding to an integrated luminosity of 4.6 fb^(−1) recorded by the CMS experiment at the LHC.
Journal ArticleDOI

S. Chatrchyan, +2177 more
- 08 Jan 2013 - 
TL;DR: In this article, the first study of isolated photon + jet correlations in relativistic heavy ion collisions is reported using data from PbPb collisions at a centre-of-mass energy of 2.76 TeV2.
Journal ArticleDOI

Constraints on the Higgs boson width from off-shell production and decay to Z-boson pairs

Vardan Khachatryan, +2204 more
- 07 Sep 2014 - 
TL;DR: In this article, the authors presented an analysis on the total width of the recently discovered Higgs boson, Gamma[H], using its relative on-shell and off-shell production and decay rates to a pair of Z bosons, where one Z boson decays to an electron or muon pair, and the other to a neutrino pair.
