The production of isolated photons in PbPb and pp collisions at $$ \sqrt{s_{\mathrm{NN}}} $$ = 5.02 TeV

Albert M. Sirunyan, +2375 more

- 17 Jul 2020

- Journal of High Energy Physics

TL;DR: In this article, the transverse energy spectra of photons isolated from other particles are measured using proton-proton (pp) and lead-lead (PbPb) collisions at the LHC at $ \sqrt{s_{\mathrm{NN}}} = 5.02 TeV with integrated luminosities of 27.4 pb$−1}$ and 404 μb$ −1}

Constraints on the $\chi_\mathrm{c1}$ versus $\chi_\mathrm{c2}$ polarizations in proton-proton collisions at $\sqrt{s} =$ 8 TeV

Albert M. Sirunyan, +2306 more

- 01 Jan 2020

- Physical Review Letters

TL;DR: In this article, the polarizations of the mesons produced by the LHC at s = 8'TeV were measured in the helicity frame, through the analysis of the χc2 to χ c1 yield ratio as a function of the polar or azimuthal angle of the positive muon emitted in the J/ψ→μ+μ- decay, in three bins of J /ψ transverse momentum.

First measurement of the cross section for top quark pair production with additional charm jets using dileptonic final states in pp collisions at √{ s } = 13TeV

Albert M. Sirunyan, +2324 more

- 10 Sep 2021

- Physics Letters B

TL;DR: In this paper, the first measurement of the inclusive cross section for top quark pairs ( t t ) produced in association with two additional charm jets is presented. But the results are not consistent with predictions from two different matrix element generators with next-to-leading order accuracy in quantum chromodynamics, interfaced with a parton shower simulation.

Search for the lepton flavor violating decay τ → 3μ in proton-proton collisions at √s = 13 TeV

Albert M. Sirunyan, +2476 more

- 26 Jan 2021

- Journal of High Energy Physics

TL;DR: In this paper, a search for the lepton flavor violating decay τ → 3μ in proton-proton collisions at 13 TeV was carried out at the LHC, where τ leptons produced in both W boson and heavy-flavor hadron decays were exploited.

Hard color-singlet exchange in dijet events in proton-proton collisions at s =13 TeV

Albert M. Sirunyan, +2499 more

- 01 Aug 2021

- Physical Review D

TL;DR: In this article, the authors studied jet-gap-jet events in proton-proton collisions at the CERN LHC with an intact proton using a subsample of events with an integrated luminosity of 0.4-1.0%.
