Description

Due to their large mass, heavy quark pairs are considered to be produced in the first instants of the collision in hard scatterings of partons which can be described perturbatively. However, the bound states of these pairs are produced via soft non-perturbative processes. The interplay between the perturbative and non-perturbative processes involved in quarkonium production makes this field a very important testing ground for QCD. At the LHC, the special setup of the ALICE experiment allows the study of charmonium production in pp collisions down to zero transverse momentum in a large rapidity range, $|y|<0.9$ and $2.5
