Description
Generalized Parton Distributions (GPDs) are fundamental quantum correlation functions of quarks and gluons (collectively referred to as partons) inside hadrons and encode rich information that can unravel many aspects of the confined hadron structure, such as quark and gluon tomography, as well as emergent hadronic properties, including the mechanical properties and spin and mass decompositions. In this presentation, I will give a brief overview on the theory and phenomenology of GPDs, as well as physical processes that are sensitive to GPDs. I will concentrate on the extraction of GPDs from experimental observables, especially on the challenges and potential solutions regarding the separation of different GPDs and the extraction of $x$-dependence of GPDs, which is critically important for constructing the tomographic images of hadrons and for matching the $x$-moments of GPDs to various emergent hadron properties.
