| Abstract: | The production cross-sections of J/ψ mesons in proton-proton collisions at a centreof-mass energy of √ s = 5 TeV are measured using a data sample corresponding to an integrated luminosity of 9.13 ± 0.18 pb−1 , collected by the LHCb experiment. 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, |
