| Publication Abstract: | The strong nuclear force which binds the hadrons is described by the Quantum Chromodynamic (QCD) theory. Determining the character and manifestations of the QCD theory is one of the most important and challenging outstanding issues necessary for a comprehensive understanding of the structure of hadrons. Within the context of the QCD parton model, the Parton Distribution Functions (PDFs) have been remarkably successful in describing a wide variety of processes. However, these PDFs have generally been confined to the description of collinear partons within the hadron. New experiments and facilities provide the opportunity to additionally explore the transverse structure of the hadrons which are described by Generalized Parton Distributions (GPDs) and Transverse Momentum Dependent Parton Distribution Functions (TMD PDFs). In our previous review (Lin et al., 2018d) we compared and contrasted the two main approaches used to determine the collinear PDFs: the first based on the perturbative QCD factorization theorems, and the second based on lattice QCD calculations. In the present study, we provide a brief update of recent progress on the collinear PDFs, and also expand the scope to encompass the generalized PDFs (GPDs and TMD PDFs). We review the current state of the various calculations, and consider what new data might be available in the near future. We also examine how a shared effort can foster dialog between the PDF and Lattice QCD communities, and yield improvements for these generalized PDFs. |
