Description

Deep virtual exclusive [electroproduction] scattering (DVES) is predicted to provide access to novel tomographic distributions of quarks and gluons inside nucleons, nuclei, and other hadrons. I will discuss recent progress in both virtual Compton scattering (DVCS) and deep virtual meson production on the nucleon and on nuclei, Including recent data from Jefferson Lab and COMPASS. In DVCS, measurements of spin observables and energy-dependent cross sections allow the separation of the Re and Im parts of the DVCS amplitude. Neutron observables are obtained from tagged and untagged DVES measurements on deuterium.

A new exclusive 4He experiment is in progress with CLAS12 at JLab.
I will discuss some of the unique opportunities for DVES studies with the future Electron Ion Collider.
