Deeply virtual Compton scattering with CLAS12

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

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 CLAS collaboration at JLab plays a key role in the extraction of GPDs from deep exclusive processes, in particular from deeply virtual Compton scattering (DVCS). This topic is at the heart of the physics program for the upcoming JLab machine upgrade to 12 GeV. In this report, we present the future CLAS12 detector and the simulations that have been carried out for the DVCS process. We show how the various combinations of beam and target polarization observables will constrain the GPDs or Compton Form Factors extractions.
