Measurement of DVCS Cross Section off Protons with CLAS12

ORAL

Abstract

We present a status report on the proton DVCS differential cross-section using the CLAS12 detector at Jefferson Lab. The DVCS process involves deeply inelastic electroproduction of real photons in the scattering from the struck quark inside the proton. The extracted cross-section enables three-dimensional imaging of the proton structure in the framework of GPDs. The experiment utilized a 5 cm long, unpolarized, liquid hydrogen target, the CEBAF 10.6 GeV polarized electron beam, and state-of-the-art particle detectors located in a magnetic field produced by a solenoid and torus, which enabled particle identification and momentum reconstruction. We will also discuss the physical interpretation of the measurement.
