According to theoretical predictions charmonium production in nucleus-nucleus collisions at LHC energy could be a nice example of interplay between “hard” and “soft” aspects of QCD interactions. In fact the c and ¯c quarks are indubitably produced in “hard” partonic scattering, but a new “soft” mechanism at LHC could become relevant for the charmonium production in Pb-Pb collisions: “coalescence” may lead free c and ¯c quarks in the QGP to recombine into charmonium mesons. The ALICE detector at LHC will measure charmonium production both at central and forward rapidity using two different decay channels, and reaching in both cases down to pT = 0. The first results in proton-proton collisions for the charmonium measurements will be discussed in this contribution.
