Abstract

Generalized parton distributions (GPDs) are nowadays the object of an intense effort of research. Among other aspects, they allow to unravel the correlation between the longitudinal momentum fraction and the transverse spatial distributions of quarks and gluons inside the nucleon, with the prospect of accessing the angular momentum contribution of the partons to the nucleon's spin. The Hall A and CLAS Collaborations of Jefferson Lab, or JLab, play a key role in the extraction of GPDs from deeply virtual Compton scattering (DVCS) and from deeply virtual meson production (DVMP). This topic is at the heart of the physics program for the upcoming JLab machine upgrade to 12 GeV. This report presents an overview (with a large focus on DVCS) of published results and ongoing analyses from JLab 6GeV data, and future experiments planned at JLab 12GeV, in Hall A and with the future CLAS12 detector in Hall B.
