Abstract
We present results on transverse momentum () and rapidity () differential production cross sections, mean transverse momentum and mean transverse momentum square of inclusive and at forward rapidity () as well as-to- cross section ratios. These quantities are measured in pp collisions at center of mass energies and 13 TeV with the ALICE detector. Both charmonium states are reconstructed in the dimuon decay channel, using the muon spectrometer. A comprehensive comparison to inclusive charmonium cross sections measured at, 7 and 8 TeV is performed. A comparison to non-relativistic quantum chromodynamics and fixed-order next-to-leading logarithm calculations, which describe prompt and non-prompt charmonium production respectively, is also presented. A good description of the data is obtained over the full range, provided that both contributions are summed. In particular, it is found that for GeV/c the non-prompt contribution reaches up to 50% of the total charmonium yield.
