Title: Forward $J / ψ$ production at high energy: Centrality dependence and mean transverse momentum

Abstract

Forward rapidity J/$$\psi$$ meson production in proton-nucleus collisions can be an important constraint of descriptions of the small- x nuclear wave function. In an earlier work we studied this process using a dipole cross section satisfying the Balitsky-Kovchegov equation, fit to HERA inclusive data and consistently extrapolated to the nuclear case using a standard Woods-Saxon distribution. In this paper we present further calculations of these cross sections, studying the mean transverse momentum of the meson and the dependence on collision centrality. We also extend the calculation to backward rapidities using nuclear parton distribution functions. Here, we show that the parametrization is overall rather consistent with the available experimental data. However, there is a tendency towards a too strong centrality dependence. This can be traced back to the rather small transverse area occupied by small- x gluons in the nucleon that is seen in the HERA data, compared to the total inelastic nucleon-nucleon cross section.

The double-differential cross sections of promptly produced J/ψ and ψ(2S) mesons are measured in pp collisions at √s = 7 TeV, as a function of transverse momentum p_T and absolute rapidity |y|. The analysis uses J/ψ and ψ(2S) dimuon samples collected by the CMS experiment, corresponding to integrated luminosities of 4.55 and 4.90 fb_–1, respectively. The results are based on a two-dimensional analysis of the dimuon invariant mass and decay length, and extend to p_T = 120 and 100 GeV for the J/ψ and ψ(2S), respectively, when integrated over the interval |y| < 1.2.

Measurements of differential cross sections for J/ψ production in p+Pb collisions at √s_NN=5.02TeV at the CERN Large Hadron Collider with the ATLAS detector are presented. The data set used corresponds to an integrated luminosity of 28.1 nb^-1. The J/ψ mesons are reconstructed in the dimuon decay channel over the transverse momentum range 8<30GeV and over the center-of-mass rapidity range -2.87<1.94. Prompt J/ψ are separated from J/ψ resulting from b-hadron decays through an analysis of the distance between the J/ψ decay vertex and the event primary vertex. The differential cross section for production of nonprompt J/ψ is compared to a FONLLmore »« less

Forward $J / ψ$ production in U + U collisions at $\sqrt{s_{N N}} = 193$ GeV

Journal Article Adare, A. ; Aidala, C. ; Ajitanand, N. N. ; ... - Physical Review C

Here, the invariant yields, dN/dy, for J/ψ production at forward rapidity (1.2 < |y| < 2.2) in U+U collisions at √^SNN=193GeV have been measured as a function of collision centrality. The invariant yields and nuclear-modification factor R_AA are presented and compared with those from Au+Au collisions in the same rapidity range. Additionally, the direct ratio of the invariant yields from U + U and Au + Au collisions within the same centrality class is presented, and used to investigate the role of cc¯ coalescence. Two different parametrizations of the deformed Woods-Saxon distribution were used in Glauber calculations to determine themore »« less
