AB We present results on transverse momentum(pt) and rapidity (y) differential production cross sections,mean transverse momentum and mean transverse momentumsquare of inclusive J/ψ and ψ(2S) at forward rapidity(2.5 < y < 4) as well as ψ(2S)-to-J/ψ cross sectionratios. These quantities are measured in pp collisions at centerof mass energies√s = 5.02 and 13 TeV with the ALICEdetector. Both charmonium states are reconstructed in thedimuon decay channel, using the muon spectrometer.Acomprehensivecomparison to inclusive charmonium cross sectionsmeasured at√s = 2.76, 7 and 8 TeV is performed.A comparison to non-relativistic quantum chromodynamicsand fixed-order next-to-leading logarithm calculations,which describe prompt and non-prompt charmonium productionrespectively, is also presented. A good description ofthe data is obtained over the full pt range, provided that bothcontributions are summed. In particular, it is found that forpt > 15 GeV/c the non-prompt contribution reaches up to50% of the total charmonium yield.
