Abstract (english)
The PHENIX experiment at the Relativistic Heavy Ion Collider has measured the differential cross section, mean transverse momentum, mean transverse momentum squared of inclusive J=ψ, and cross section ratio of ψ(2S) to J/ψ at forward rapidity in p + p collisions at √s = 510 GeV via the dimuon decay channel. Comparison is made to inclusive J=ψ cross sections measured at √s = 200 GeV and 2.76–13 TeV. The result is also compared to leading-order nonrelativistic QCD calculations coupled to a color-glass-condensate description of the low-x gluons in the proton at low transverse momentum (pT) and to next-to-leading order nonrelativistic QCD calculations for the rest of the pT range. These calculations overestimate the data at low pT. While consistent with the data within uncertainties above ≈3 GeV=c, the calculations are systematically below the data. The total cross section times the branching ratio is BR dσ^J/ψ_pp / dy(1.2 < |y| < 2.2, 0 < pT < 10 GeV/c) = 54.3 ± 0.5 (stat) ± 5.5 (syst) nb.
