Measurements of t(t)over-bar spin correlations and top quark polarization using dilepton final states in pp collisions at root s=8 TeV

Khachatryan, +2258 more
- 09 Mar 2016 - 
TL;DR: Spin correlations and polarization in the top quark-antiquark system are measured using dilepton final states produced in pp collisions at the LHC at root s = 7 TeV as discussed by the authors.
Journal ArticleDOI

Search for supersymmetry in events with b jets and missing transverse momentum at the LHC

S. Chatrchyan, +2231 more
- 01 Jul 2011 - 
TL;DR: In this paper, a search for supersymmetry using a sample of events with b jets and missing transverse momentum is presented using a data sample of proton-proton collisions at a centre-of-mass energy of 7 TeV, corresponding to an integrated luminosity of 35 inverse picobarns.
Journal ArticleDOI

Search for pair production of vector-like T and B quarks in single-lepton final states using boosted jet substructure in proton-proton collisions at √s = 13 TeV

Albert M. Sirunyan, +2291 more
- 01 Nov 2017 - 
TL;DR: In this article, a search for pair production of massive vector-like T and B quarks in proton-proton collisions at root s = 13 TeV is presented.
Journal ArticleDOI

Search for standard model production of four top quarks with same-sign and multilepton final states in proton–proton collisions at √s=13TeV

Albert M. Sirunyan, +2249 more
- 19 Feb 2018 - 
TL;DR: A search for standard model production of four top quarks is reported using events containing at least three leptons, using results to constrain the Yukawa coupling between the top quark and the Higgs boson to be less than 2.1 times its expected standard model value at 95% confidence level.
Journal ArticleDOI

Search for supersymmetry in events with soft leptons, low jet multiplicity, and missing transverse energy in proton-proton collisions at s=8 TeV

Vardan Khachatryan, +2315 more
- 10 Aug 2016 - 
TL;DR: In this article, a search for supersymmetric particles in scenarios with a compressed mass spectrum was conducted, where the neutralino was assumed to be the lightest super-symmetric particle (LSP).
