The cross-sections are measured differentially as a function of transverse momentum, pT, and rapidity, y, and separately for J/ψ mesons produced promptly and from beauty hadron decays (nonprompt). With the assumption of unpolarised J/ψ mesons, the production cross-sections integrated over the kinematic range 0 < pT < 20 GeV/c and 2.0 < y < 4.5 are σprompt J/ψ = 8.154 ± 0.010 ± 0.283 µb, σnonprompt J/ψ = 0.820 ± 0.003 ± 0.034 µb,35 p.application/pdfengcc-by (c) LHCb Collaboration et al., 2021https://creativecommons.org/licenses/by/4.0/HadronsGran Col·lisionador d'HadronsFísica de partículesExperimentsHadronsLarge Hadron Collider (France and Switzerland)Particle physicsExperimentsinfo:eu-repo/semantics/article7210662022-05-10info:eu-repo/semantics/openAccess
