Forward rapidity J=ψ 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. 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.

Centrality-dependent forward J/ψ production in high energy proton-nucleus collisions
Ducloue, Bertrand; Lappi, Tuomas; Mäntysaari, H. (EDP Sciences, 2016)Forward J/ψ production and suppression in high energy proton-nucleus collisions can be an important probe of gluon saturation. In an earlier work we studied this process in the Color Glass Condensate framework and showed ... -
Forward J /ψ production in proton-nucleus collisions at high energy
Ducloue, Bertrand; Lappi, Tuomas; Mäntysaari, Heikki (American Physical Society, 2015)Inclusive production of J/ψ mesons, especially at forward rapidities, is an important probe of small-x gluons in protons and nuclei. In this paper we reevaluate the production cross sections in the color glass condensate ... -
Forward rapidity isolated photon production in proton-nucleus collisions
Ducloué, B.; Lappi, Tuomas; Mäntysaari, Heikki (Elsevier BV, 2019)We calculate isolated photon production at forward rapidities in proton-nucleus collisions in the Color Glass Condensate framework. Our calculation uses dipole cross sections solved from the running coupling Balitsky-Kovchegov ... -
Forward J/ψ production in pA collisions : centrality dependence
Ducloue, Bertrand; Lappi, Tuomas; Mäntysaari, H. (Sissa, 2016)The nuclear suppression of forward J/ψ production in high energy proton-nucleus collisions can be used as a probe of gluon saturation at small x. In an earlier work we studied this suppression in minimum bias collisions ... -
Centrality and transverse momentum dependence of inclusive J/ψ production at midrapidity in Pb–Pb collisions at √sNN = 5.02 TeV
ALICE collaboration (Elsevier, 2020)The inclusive J/ψ meson production in Pb–Pb collisions at a center-of-mass energy per nucleon–nucleon collision of √sNN=5.02TeV at midrapidity (|y| <0.9) is reported by the ALICE Collaboration. The measurements are performed ...
