Energy dependence of forward-rapidity J/ψ and ψ(2S) production in pp collisions at the LHC. Eur. Phys. J. C 77, 392 (2017). https://doi.org/10.1140/epjc/s10052-017-4940-41434-6044http://hdl.handle.net/10347/22492We present results on transverse momentum (pt) and rapidity (y) differential production cross sections, mean transverse momentum and mean transverse momentum square of inclusive J/ψ and ψ(2S) at forward rapidity (2.5 < y < 4) as well as ψ(2S)-to-J/ψ cross section ratios. These quantities are measured in pp collisions at center 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.Acomprehensive comparison to inclusive charmonium cross sections measured at √ s = 2.76, 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 pt range, provided that both contributions are summed. In particular, it is found that for pt > 15 GeV/c the non-prompt contribution reaches up to 50% of the total charmonium yield.eng© The Author(s) 2017. This article is an open access publication.
