Measurement of the tt¯ production cross section in pp collisions at s=7 TeV with lepton+jets final states

S. Chatrchyan, +2202 more
- 13 Mar 2013 - 
TL;DR: In this article, a measurement of the tt production cross section in pp collisions at √s = 7 TeV is presented, based on data corresponding to an integrated luminosity of 2.3 fb^(−1) collected by the CMS detector at the LHC.
Journal ArticleDOI

Search for a non-standard-model Higgs boson decaying to a pair of new light bosons in four-muon final states

S. Chatrchyan, +2247 more
- 04 Nov 2013 - 
TL;DR: In this article, a search for non-standard-model Higgs boson decays to pairs of new light bosons, each of which decays into the μ+μ− final state.
Journal ArticleDOI

Search for physics beyond the standard model in high-mass diphoton events from proton-proton collisions at √s = 13 TeV

Albert M. Sirunyan, +2267 more
- 02 Sep 2018 - 
TL;DR: In this article, a search for physics beyond the standard model is performed using a sample of high-mass diphoton events produced in proton-proton collisions at s=13 TeV.
Journal ArticleDOI

Search for disappearing tracks as a signature of new long-lived particles in proton-proton collisions at √s = 13 TeV

Albert M. Sirunyan, +2377 more
- 19 Apr 2018 - 
TL;DR: In this paper, a search for long-lived charged particles that decay within the LHC detector and produce the signature of a disappearing track is presented, which is an isolated track with missing hits in the outer layers of the silicon tracker, little or no energy in associated calorimeter deposits, and no associated hits in muon detectors.
Journal ArticleDOI

Search for charged Higgs bosons decaying into a top and a bottom quark in the all-jet final state of pp collisions at √s = 13 TeV

Albert M. Sirunyan, +2381 more
- 20 Jul 2020 - 
TL;DR: In this paper, a search for charged Higgs bosons decaying into a top and a bottom quark in the all-jet final state is presented, using LHC proton-proton collision data recorded with the CMS detector in 2016 at 13 TeV, corresponding to an integrated luminosity of 35.9 fb$−1.
