Search for a Heavy Resonance Decaying into a Z Boson and a Z or W Boson in 2ℓ2q Final States at √s = 13 TeV

Albert M. Sirunyan, +2365 more
- 18 Sep 2018 - 
TL;DR: In this article, a search was performed for heavy resonances decaying to ZZ or ZW in 2l2q final states, with two charged leptons (l = e, μ) produced by the decay of a Z boson, and two quarks produced by either W or Z bosons.
Journal ArticleDOI

Constraints on anomalous HVV couplings from the production of Higgs bosons decaying to τ lepton pairs

Albert M. Sirunyan, +2285 more
- 04 Dec 2019 - 
TL;DR: In this article, a study of anomalous HVVV interactions of the Higgs boson including its CP properties is presented, using the data from the CMS experiment at the LHC in 2016 at a center-of-mass energy of 13 TeV and correspond to an integrated luminosity of 35.9 fb(-1).
Journal ArticleDOI

Studies of charm and beauty hadron long-range correlations in pp and pPb collisions at LHC energies

Albert M. Sirunyan, +2313 more
- 10 Feb 2021 - 
TL;DR: In this article, the second Fourier harmonic coefficient (v 2 ) of the azimuthal distributions of prompt and non-prompt D0 mesons produced in p p and p Pb collisions is presented.
Journal ArticleDOI

Search for new physics in final states with a single photon and missing transverse momentum in proton-proton collisions at √s=13 TeV

Albert M. Sirunyan, +2377 more
- 13 Feb 2019 - 
TL;DR: In this article, a search was conducted for new physics in final states containing a photon and missing transverse momentum in proton-proton collisions at the LHC, where the expected lower limits on mediator masses were both 950 (1150) GeV for 1 GeV dark matter mass.
Journal ArticleDOI

Erratum: Search for anomalous tt̄ production in the highly-boosted all-hadronic final state (Journal of High Energy Physics (2012) 09 (029))

S. Chatrchyan, +2269 more
- 28 Mar 2014 - 
TL;DR: In this paper, a search for a massive particle, referred to as a Z', decaying into a t t-bar pair is presented, focusing on Z' resonances that are sufficiently massive to produce highly Lorentzboosted top quarks, which yield collimated decay products that are partially or fully merged into single jets.
