Search for new physics in events with photons, jets, and missing transverse energy in pp collisions at s√ = 7 TeV

S. Chatrchyan, +2253 more
- 19 Mar 2013 - 
TL;DR: In this paper, a search for physics beyond the standard model involving events with one or more photons, jets, and missing transverse energy has been performed by the CMS experiment, and the results of this search are interpreted in the context of three models of new physics: a general model of gauge-mediated supersymmetry breaking, Simplified Models, and a theory involving universal extra dimensions.
Journal ArticleDOI

Combined search for the quarks of a sequential fourth generation

S. Chatrchyan, +2244 more
- 12 Dec 2012 - 
TL;DR: In this paper, limits on the mass of the fourth generation quarks and the relevant Cabibbo-Kobayashi-Maskawa matrix elements are derived in the context of a simple extension of the standard model with a sequential fourth generation of fermions.
Journal ArticleDOI

Measurements of the tt¯ production cross section in lepton+jets final states in pp collisions at 8 TeV and ratio of 8 to 7 TeV cross sections

Vardan Khachatryan, +2290 more
- 07 Jan 2017 - 
TL;DR: In this article, a measurement of the top quark pair production (t-tbar) cross section in proton-proton collisions at the centre-of-mass energy of 8 TeV is presented using data collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 19.6 inverse-femtobarns.
Journal ArticleDOI

Measurements of the tt charge asymmetry using the dilepton decay channel in pp collisions at √s = 7 TeV

S. Chatrchyan, +2288 more
- 30 Apr 2014 - 
TL;DR: In this paper, the authors measured the t t-bar charge asymmetry in proton-proton collisions at 7 TeV using the dilepton decay channel (ee, e mu, or mu mu).
Journal ArticleDOI

Search for dark matter in proton-proton collisions at 8 TeV with missing transverse momentum and vector boson tagged jets

Vardan Khachatryan, +2345 more
- 16 Dec 2016 - 
TL;DR: In this article, a search for an excess of events with large missing transverse momentum in association with at least one highly energetic jet, in a data sample of proton-proton collisions at a centre-of-mass energy of 8 TeV.
