Abstract:
Hadron structure in QCD is expressed in the hadronic matrix elements of operators such as local currents (charges, form factors) or nonlocal correlators appearing in the factorization of high-momentum transfer processes (partonic structure, PDFs, GPDs). These structures can be calculated/explained/predicted using systematic non perturbative methods of strong-interaction physics such as chiral effective field theory (ChEFT), dispersion theory (analyticity, unitarity, N/D), and the 1/N expansion of QCD. We present an overview of recent results and future directions in this field.  This includes: (a) First-principles calculations of nucleon form factors combining chiral EFT and dispersion theory, with applications to JLab experiments and the proton radius extraction; (b) Partonic structure at peripheral transverse distances b ~ 1/M_pi from ChEFT (transverse densities, GPDs); (c) Energy-momentum tensor and partonic angular momentum in the nucleon. We emphasize the connections and synergies and with other fields (LQCD, amplitude analysis, baryon resonances)

Thank you.
