Abstract

Charmonium production cross-section in proton-proton collisions is measured at the centre-of-mass energy √(s)=13 TeV using decays to pp final state. The study is performed using a data sample corresponding to an integrated luminosity of 2.2 fb^-1 collected in 2018 with the LHCb detector. The production cross-section of the η_c meson is measured in a rapidity range of 2.0 < y < 4.0 and in a transverse momentum range of 5.0 < p_T < 20.0 GeV/\itc, which is extended compared with previous LHCb analyses. The differential cross-section is measured in bins of p_T and, for the first time, of y. Upper limits, at 90% and 95% confidence levels, on the η_c(2S) and h_c(1P) prompt production cross-sections are determined for the first time.
