Insights on non-perturbative aspects of TMDs from models

Abstract

Transverse momentum dependent parton distribution functions are a key ingredient in the description of spin and azimuthal asymmetries in deep-inelastic scattering processes. Recent results from non-perturbative calculations in effective approaches are reviewed, with focus on relations among different parton distribution functions in QCD and models.

Based on talks at "Transverse Partonic Structure of Hadrons", Yerevan, Armenia, 21-26 June 2009; "Recent Advances in Perturbative QCD and Hadronic Physics", ETC, Trento, Italy, 21-25 July 2009; "3D parton structure of the nucleon"," INT Seattle, WA, U.S.A. 14-18 September 2009. Dedicated to 75th birthday of A.V.Efremov by co-authors
