TMD phenomenology with the HSO approach

Abstract:
Transverse momentum dependent (TMD) observables are typically classified in terms of their contributions coming from different regions in transverse momentum. The low transverse momentum behavior is often ascribed to intrinsic nonperturbative properties of the hadron described by TMD factorization, while the large transverse momentum region can be computed using fixed order collinear perturbation theory. Combining both pictures in a consistent way presents challenges, for practical calculations as well as the interpretation of results. We discuss a recent approach that is designed to retain a physical interpretation in terms of hadron structure while alleviating tension with techniques used at much higher energies. The approach is organized to allow for convenient nonperturbative model building in a way that incorporates both perturbative and non perturbative contributions in the parametrization of TMD densities while guaranteeing the matching in the large transverse momentum region.
