The data set corresponds to an integrated luminosity of about 10μb−1. The J/ψ mesons are reconstructed in the dimuon final state, where the muons are detected within the pseudorapidity region 2.0 < η < 4.5. The J/ψ mesons are required to have transverse momentum pT < 1 GeV and rapidity 2.0 < y < 4.5. The cross-section within this fiducial region is measured to be σ = 5.3 ± 0.2 (stat) ± 0.5 (syst) ± 0.7 (lumi) mb. The differential cross-section is also measured in five bins of J/ψ rapidity. The results are compared to predictions from phenomenological models.4 p.application/pdfengcc-by-nc-nd (c) Alfonso Albero et. al., 2019http://creativecommons.org/licenses/by-nc-nd/3.0/esCol·lisions d'ions pesatsMesons (Física nuclear)Heavy ion collisionMesons (Nuclear physics)info:eu-repo/semantics/article6939242020-10-14info:eu-repo/semantics/openAccess
