Description
Generalized parton distributions (GPDs) offer a powerful framework to access the multidimensional structure of hadrons, allowing in particular for so-called nucleon tomography and providing access to elements of the hadron energy–momentum tensor. The extraction of GPDs from experimental data is, however, challenging and often cannot be performed in a complete way due to difficulties arising from the deconvolution of amplitudes. In parallel, lattice QCD has achieved notable progress in computing quantities relevant to GPDs from first principles. The growing synergy between lattice results and phenomenological models provides new opportunities for cross-validation, improved parametrizations, and enhanced predictive power.
In my talk, I will highlight recent developments in GPD phenomenology, discuss ongoing efforts to integrate lattice inputs, and outline prospects for a unified description of hadron structure through combined theoretical and experimental approaches.
