Description

We will consider quarkonium production in proton-proton and lepton-proton collisions, within a TMD approach. We will discuss the relative role of the NRQCD color-singlet and color-octet production mechanisms both in the unpolarized cross section and in the transverse single-spin asymmetries. Focus will be put on linearly polarized gluons in unpolarized and transversely polarized targets as well as on the gluon Sivers function. Their process dependence will be also addressed.
