Journal ArticleDOI

Search for anomalous tt̄ production in the highly-boosted all-hadronic final stat

S. Chatrchyan, +2268 more
- 11 Sep 2012 - 
TL;DR: In this article, a search for a massive particle, referred to as a Z′, decaying into a tt pair is presented, focusing on Z′ resonances that are sufficiently massive to produce highly Lorentz-boosted top quarks.
Journal ArticleDOI

Studies of dijet transverse momentum balance and pseudorapidity distributions in pPb collisions at √sNN = 5.02 TeV

S. Chatrchyan, +2213 more
- 23 Jul 2014 - 
TL;DR: In this paper, the pseudorapidity distribution of the dijet system in minimum bias pPb collisions is compared with next-to-leading-order perturbative QCD predictions obtained from both nucleon and nuclear parton distribution functions, and the data more closely match the latter.
Journal ArticleDOI

Search for Microscopic Black Hole Signatures at the Large Hadron Collider

Vardan Khachatryan, +2146 more
- 21 Mar 2011 - 
TL;DR: In this paper, a search for microscopic black hole production and decay in pp collisions at a center-of-mass energy of 7 TeV was conducted by the CMS Collaboration at the LHC, using a data sample corresponding to an integrated luminosity of 35 inverse picobarns.
Journal ArticleDOI

Search for the standard model Higgs boson produced through vector boson fusion and decaying to bb

Vardan Khachatryan, +2291 more
- 27 Aug 2015 - 
TL;DR: In this paper, a first search was reported for a standard model Higgs boson (H) that is produced through vector boson fusion and decays to a bottom-quark pair.
Journal ArticleDOI

Search for production of four top quarks in final states with same-sign or multiple leptons in proton-proton collisions at √{s }=13 TeV

Albert M. Sirunyan, +2295 more
- 31 Jan 2020 - 
TL;DR: The standard model (SM) production of four top quarks in proton-proton collisions is studied by the CMS Collaboration, with limits set on the production of a heavy scalar or pseudoscalar boson in Type-II two-Higgs-doublet and simplified dark matter models.
