Abstract (data abstract)
CERN-LHC. We present ALICE results on transverse momentum ($p_{\rm T}$) and rapidity ($y$) differential production cross sections, mean transverse momentum and mean transverse momentum square of inclusive $J/\psi$ and $\psi(2S)$ at forward rapidity (2.5 < $y$ < 4) as well as $\psi(2S)$-to-$J/\psi$ cross section ratios. These quantities are measured in pp collisions at center of mass energies $\sqrt{s}$ = 5.02 and 13 TeV. Both charmonium states are reconstructed in the dimuon decay channel, using ALICE muon spectrometer.
