Exclusive and semi-exclusive pi+pi- production in proton-proton collisions at sqrt(s) = 7 TeV

Vardan Khachatryan, +2254 more
TL;DR: In this paper, a measurement of the exclusive and semi-exclusive production of charged pion pairs in proton-proton collisions is presented, where the pi+pi-pair is emitted at central rapidities, and scattered protons stay intact (p) or diffractively dissociate (p*) without detection.
Journal ArticleDOI

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 - 
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.
Journal ArticleDOI

Search for W Boson Decays to Three Charged Pions

Albert M. Sirunyan, +2276 more
- 18 Apr 2019 - 
TL;DR: Proton-proton collision data recorded by the CMS experiment at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 77.3 fb^{-1], have been analyzed and no significant excess is observed above the background expectation.
Journal ArticleDOI

Using Z Boson Events to Study Parton-Medium Interactions in Pb-Pb Collisions.

Albert M. Sirunyan, +2284 more
- 23 Mar 2022 - 
TL;DR: The spectra measurements of charged hadrons produced in the shower of a parton originating in the same hard scattering with a leptonically decaying Z boson are reported in lead-lead nuclei (Pb-Pb) and proton-proton (pp) collisions at a nucleon-nucleon center-of-mass energy of 5.02-TeV as discussed by the authors .
Journal ArticleDOI

Measurement of prompt D-0 and D-0 meson azimuthal anisotropy and search for strong electric fields in PbPb collisions at root S-NN=5.02 TeV

Albert M. Sirunyan, +2373 more
- 10 May 2021 - 
TL;DR: In this article, the strong Coulomb field created in ultrarelativistic heavy ion collisions is expected to produce a rapidity-dependent difference ( Δv2 ) in the second Fourier coefficient of the azimuthal distribution (elliptic flow, v2 ) between D0 ( uc ) and D´0( uc) mesons.
