Abstract: (Springer)

Charmonium production cross-section in proton–proton collisions is measured at the centre-of-mass energy

\sqrt{s}=13\,\textrm{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\,\textrm{fb}^{-1}

collected in 2018 with the

\text{ LHCb }

detector. The production cross-section of the

\eta _c

meson is measured in a rapidity range of

2.0< y < 4.0

and in a transverse momentum range of

5.0< p_{\textrm{T}} < 20.0\,\textrm{GeV}\!/\!{ c}

, which is extended compared with previous

\text{ LHCb }

analyses. The differential cross-section is measured in bins of

p_\mathrm{{T}}

and, for the first time, of y. Upper limits, at 90% and 95% confidence levels, on the

\eta _c(2S)

and

h_c(1P)

prompt production cross-sections are determined for the first time.
