Distributions of topological observables in inclusive three- and four-jet events in pp collisions at √s=7 TeV

Vardan Khachatryan, +2192 more
- 01 Jul 2015 - 
TL;DR: In this article, the distributions of topological observables in inclusive three and four-jet events produced in pp collisions at a centre-of-mass energy of 7 TeV with a data sample collected by the CMS experiment corresponding to a luminosity of 5.1 inverse femtobarns are presented.
Journal ArticleDOI

Search for top squark pair production in a final state with two tau leptons in proton-proton collisions at √s = 13 TeV

Albert M. Sirunyan, +2412 more
- 03 Feb 2020 - 
TL;DR: In this paper, a search for pair production of the supersymmetric partner of the top quark, the top squark, in proton-proton collision events at 13 TeV is presented in a final state containing hadronically decaying tau leptons and large missing transverse momentum.
Journal ArticleDOI

Search for natural supersymmetry in events with top quark pairs and photons in pp collisions at √s=8 TeV

Albert M. Sirunyan, +2297 more
- 27 Mar 2018 - 
TL;DR: In this article, a search for natural gauge-mediated supersymmetry (SUSY) in a scenario in which the top squark is the lightest squark, the next-to-lightest SUSY particle is a bino-like neutralino, and the gravitino is the heavy gravite.

Measurements of the ZZ production cross sections in the 2l2ν channel in proton–proton collisions at √s = 7 and 8 TeV and combined constraints on triple gauge couplings

Vardan Khachatryan, +2114 more
TL;DR: In this paper, the authors reconstructed the leptonic decay mode ZZ → 2l2ν, where l denotes an electron or a muon, from data corresponding to an integrated luminosity of 5.1+1.1 (19.6) fb−1 at 7 (8) TeV collected with the CMS experiment.
