Descripción
We study the J/ψ production at small transverse momenta at lepton-hadron colliders in the limit when the exchange photon is real, i.e. leptoproduction. In this talk I discuss the TMD factorization of the cross-section of that process in terms of the so-called TMD Shape Functions (TMDShFs), the promoted LDMEs when the transverse momentum becomes relevant. I then discuss our results for the TMDShFs at next-to-leading order, the evolution of them and the matching onto the LDMEs at large transverse momentum region. In the end, I discuss the hard part of the process.
