Abstract

We present results on transverse momentum (pt) and rapidity (y) differential production cross sections, mean transverse momentum and mean transverse momen- tum square of inclusive J/ψ and ψ(2S) at forward rapid- ity (2.5 < y < 4) as well as ψ(2S)-to-J/ψ cross section ratios. These quantities are measured in pp collisions at cen- ter of mass energies √s = 5.02 and 13 TeV with the ALICE detector. Both charmonium states are reconstructed in the dimuon decay channel, using the muon spectrometer. A com- prehensive comparison to inclusive charmonium cross sec- tions measured at √s = 2.76, 7 and 8 TeV is performed. A comparison to non-relativistic quantum chromodynam- ics and fixed-order next-to-leading logarithm calculations, which describe prompt and non-prompt charmonium pro- duction respectively, is also presented. A good description of the data is obtained over the full pt range, provided that both contributions are summed. In particular, it is found that for pt > 15 GeV/c the non-prompt contrib
