We present a detailed study, performed in the framework of LO perturbativeQCD with the inclusion of spin and k_T effects, of unpolarized cross sectionsfor the Drell-Yan process and for inclusive pion and photon production inhadronic collisions, in different kinematical situations. We find asatisfactory agreement between theoretical predictions and experimental data.This supports the study of spin effects and transverse single spin asymmetries(SSA) within the same scheme. We then present results for SSA, generated by theso-called Sivers effect, in inclusive pion production in proton-protoncollisions.Comment: LaTeX2e, 4 pages, 4 ps figures, uses ws-procs9x6.
