Quarkonia are mesons formed of either a charm and anti-charm quark pair (J/ψ, ψ(2S)) or a beauty and anti-beauty quark pair (ϒ(1S), (2S) and (3S)). We report on forward rapidity (2:5 < y < 4) J/ψ and ψ(2S) production measured in pp collisions at √s = 13 TeV, using data collected at the LHC in 2015. The results will be compared with similar measurements performed at √s = 2.76, 5.02, 7 and 8 TeV. They will be further compared to NRQCD and FONLL calculations, which describe prompt and non-prompt charmonium production respectively. Results of the J/ψ nuclear modification factor as a function of collision centrality in p–Pb collisions at = 8.16 TeV, at forward and backward rapidities, will also be presented. These measurements will be compared with Run-1 (2009 – 2013) results as well as theoretical calculations and will be interpreted in terms of cold nuclear matter effects.
