Measurement of the t̄t production cross section in the all-jet final state in pp collisions at √s=7 TeV

S. Chatrchyan, +2258 more
- 14 May 2013 - 
TL;DR: In this article, a measurement of the tt− production cross section (σtt−) in proton-proton collisions at a centre-of-mass energy of 7 TeV, in the all-jet final state that contains at least six jets, two of which are tagged as originating from b quarks.
Journal ArticleDOI

Search for supersymmetry in electroweak production with photons and large missing transverse energy in pp collisions at √s=8TeV

Vardan Khachatryan, +2287 more
- 10 Aug 2016 - 
TL;DR: In this paper, a search for supersymmetry with gauge-mediated supersymmetric breaking in electroweak production was conducted, in which the lightest neutralino has bino-or wino-like components and decays to photons and gravitinos.
Journal ArticleDOI

Search For New Physics In Top Quark Production In Dilepton Final States In Proton-Proton Collisions At Root S=13 Tev

Albert M. Sirunyan, +2254 more
- 01 Nov 2019 - 
TL;DR: This analysis differs from previous searches for new physics in the top quark sector by explicitly separating t W from t t ¯ events and exploiting the specific sensitivity of the t W process to new physics.
Journal ArticleDOI

Measurement of the inclusive and differential Higgs boson production cross sections in the leptonic WW decay mode at √s = 13 TeV

Albert M. Sirunyan, +2385 more
- 01 Mar 2021 - 
TL;DR: In this paper, the authors measured the fiducial and differential production cross sections of the Higgs boson in proton-proton collisions at 13 TeV using events where a Higgs particle decays into a pair of W bosons that subsequently decay into a final state with an electron, a muon, and a couple of neutrinos.
Journal ArticleDOI

A search for new phenomena in pp collisions at √s=13TeV in final states with missing transverse momentum and at least one jet using the αT variable

Vardan Khachatryan, +2264 more
- 08 May 2017 - 
TL;DR: The number of observed candidate events is found to agree with the expected contributions from standard model processes, and the result is interpreted in the mass parameter space of fourteen simplified supersymmetric models that assume the pair production of gluinos or squarks and a range of decay modes.
