| Sumario: | The factorization theorem for qT spectra in Drell-Yan processes, boson production and semi-inclusive deep inelastic scattering allows for the determination of the non-perturbative parts of transverse momentum dependent parton distribution functions. Here we discuss the fit of Drell-Yan and Z-production data using the transverse momentum dependent formalism and the resummation of the evolution kernel. We find a good theoretical stability of the results and a final chi(2)/points less than or similar to 1. We show how the fixing of the non-perturbative pieces of the evolution can be used to make predictions at present and future colliders. |
