Abstract
Charmonium production cross-section in proton–proton collisions is measured at the centre-of-mass energy $\sqrt{s} = 13 TeV$ using decays to $p \bar{p}$ 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 $5.0 < p_{T} < 20.0 GeV / c$ , 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 $η_{c} (2 S)$ and $h_{c} (1 P)$ prompt production cross-sections are determined for the first time.
