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
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).
Journal ArticleDOI

Search for a Vectorlike Quark with Charge2/3int+ZEvents fromppCollisions ats=7TeV

S. Chatrchyan, +2229 more
Journal ArticleDOI

Search for new physics in events with opposite-sign leptons, jets, and missing transverse energy in pp collisions at s=7 TeV

S. Chatrchyan, +2194 more
- 08 Jan 2013 - 
TL;DR: In this article, a search for physics beyond the standard model (BSM) in final states with a pair of opposite sign isolated leptons accompanied by jets and missing transverse energy is presented.
