Ratios of dijet production cross sections as a function of the absolute difference in rapidity between jets in proton-proton collisions at sqrt(s) = 7 TeV

S. Chatrchyan, +4042 more
- 16 Nov 2012 - 
TL;DR: In this paper, a study of dijet production in proton-proton collisions was performed at 7 TeV for jets with p > 35 GeV and p < 4.7 using data collected with the CMS detector at the LHC in 2010.
Journal ArticleDOI

Search for anomalous couplings in boosted WW/WZ→ℓνqq‾ production in proton-proton collisions at s=8 TeV

Albert M. Sirunyan, +2244 more
- 10 Sep 2017 - 
TL;DR: In this article, a search for anomalous triple gauge couplings in WW and WZ diboson production in proton-proton collisions is performed using events containing a W boson that decays leptonically and a W or Z boson whose decay products are merged into a single reconstructed jet.
Journal ArticleDOI

Measurement of the t t ¯ production cross section using events in the e μ final state in pp collisions at √s=13 TeV

Vardan Khachatryan, +2256 more
- 20 Mar 2017 - 
TL;DR: In this paper, the cross section of top quark-antiquark pair production in proton-proton collisions at the LHC was measured by the CMS experiment at LHC, using data corresponding to an integrated luminosity of 2.2.
Journal ArticleDOI

Measurement of t t ¯ normalised multi-differential cross sections in pp collisions at √s=13TeV , and simultaneous determination of the strong coupling strength, top quark pole mass, and parton distribution functions

Albert M. Sirunyan, +2249 more
- 22 Jul 2020 - 
TL;DR: In this article, a triple-differential measurement is performed as a function of the invariant mass and rapidity of the top quark system and the multiplicity of additional jets at particle level.
Journal ArticleDOI

Measurement of jet substructure observables in $\mathrm{t\overline{t}}$ events from proton-proton collisions at $\sqrt{s}=$ 13TeV

Albert M. Sirunyan, +2272 more
- 22 Aug 2018 - 
TL;DR: In this article, a measurement of jet substructure observables is presented using tt¯ events in the lepton+jets channel from proton-proton collisions at s=13 ǫTeV recorded by the CMS experiment at the LHC.
