Charmonium production cross-section in proton–proton collisions is measured at the centre-of-mass energy using decays to
final state. The study is performed using a data sample corresponding to an integrated luminosity of
collected in 2018 with the
detector. The production cross-section of the
meson is measured in a rapidity range of
and in a transverse momentum range of
, which is extended compared with previous
analyses. The differential cross-section is measured in bins of
and, for the first time, of y. Upper limits, at 90% and 95% confidence levels, on the
and
prompt production cross-sections are determined for the first time.
