Abstract

The inclusive production cross sections at forward rapidity of J/ψ, ψ(2S), Υ (1S) and Υ (2S) are measured in pp collisions at s √ =7 TeV with the ALICE detector at the LHC. The analysis is based on a data sample corresponding to an integrated luminosity of 1.35 pb -1 . Quarkonia are reconstructed in the dimuon-decay channel and the signal yields are evaluated by fitting the μ+ μ- invariant mass distributions. The differential production cross sections are measured as a function of the transverse momentum p T and rapidity y, over the ranges 0
