Description
I will address the study of semi-inclusive deep inelastic scattering cross sections over a wide range of transverse momenta, and in particular in the region of low to moderate $q_T$, when the interplay between perturbative and non-perturbative effects becomes more relevant. Some realistic SIDIS kinematical configuration will be considered where the commonly used prescription of matching through the so-called Y-factor cannot be applied. Moreover, I will discuss the theoretical uncertainties of the transverse momentum resummed cross sections in the CSS formalism related to the scale parameters C_1, C_2 and C_3, and their interplay with the uncertainties of the non perturbative parameters g_1, g_2 and g_3.
