Search for heavy Majorana neutrinos in same-sign dilepton channels in proton-proton collisions at √s=13 TeV

Albert M. Sirunyan, +2395 more
- 15 Jan 2019 - 
TL;DR: In this paper, a search is performed for a heavy Majorana neutrino (N), produced in leptonic decay of a W boson propagator and decaying into a W-broson and a lepton, with the CMS detector at the LHC.
Journal ArticleDOI

Search for microscopic black holes in pp collisions at $s$ = 8 TeV

S. Chatrchyan, +2256 more
- 12 Apr 2012 - 
TL;DR: In this article, a search for microscopic black holes in pp collisions at a center-of-mass energy of 7 TeV is presented, which corresponds to an integrated luminosity of 4.7 inverse femtobarns recorded by the LHC in 2011.
Journal ArticleDOI

Measurement of the cross section for top quark pair production in association with a W or Z boson in proton-proton collisions at √s = 13 TeV

Albert M. Sirunyan, +2318 more
- 03 Aug 2018 - 
TL;DR: In this article, a measurement of the cross section of top quark pair production in association with a W or Z boson using proton-proton collisions at a center-of-mass energy of 13 TeV at the LHC is performed.
Journal ArticleDOI

Search for Flavor-Changing Neutral Currents in Top-Quark Decays $t \to Zq$ in $pp$ Collisions at $\sqrt{s}=8$ TeV

S. Chatrchyan, +2183 more
- 02 May 2014 - 
TL;DR: In this paper, a search for flavor-changing neutral currents in top-quark decays t to Zq is performed in events produced from the decay chain t t-bar to Z q+Wb, where both vector bosons decay leptonically, producing a final state with three leptons (electrons or muons).
Journal ArticleDOI

Search for the standard model Higgs boson produced in association with a top-quark pair in pp collisions at the LHC

S. Chatrchyan, +2243 more
- 04 Mar 2013 - 
TL;DR: In this article, a search for the standard model Higgs boson produced in association with a top-quark pair is presented using data samples corresponding to an integrated luminosity of 5.0 fb−1 (5.1 fb −1) collected in pp collisions at the center-of-mass energy of 7 TeV (8 TeV).
