Abstract

The production cross-sections of J/ mesons in proton-proton collisions at a centre-of-mass energy of $$ \sqrt{s} $$= 5 TeV are measured using a data sample corresponding to an integrated luminosity of 9.13 ± 0.18 pb1, 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/ mesons produced promptly and from beauty hadron decays (nonprompt). With the assumption of unpolarised J/ mesons, the production cross-sections integrated over the kinematic range 0 < pT < 20 GeV/c and 2.0 < y < 4.5 arepromptJ/=8.154±0.010±0.283b,nonpromptJ/=0.820±0.003±0.034b,$$ {\displaystyle \begin{array}{c}{\sigma}_{\mathrm{prompt}}\ J/\psi =8.154\pm 0.010\pm 0.283\ \upmu \mathrm{b},\\ {}{\sigma}_{\mathrm{nonprompt}}\ J/\psi =0.820\pm 0.003\pm 0.034\ \upmu \mathrm{b},\end{array}} $$
