Abstract:
We propose to use the High Momentum Spectrometer of Hall C combined with the Neutral Particle Spectrometer (NPS) to perform high precision measurements of theDeeplyVirtual Compton Scattering (DVCS) cross section using a beam of positrons. The combination ofmeasurements with oppositely charged incident beams is the only unambiguous way to disentangle the contribution of the DVCS2 term in the photon electroproduction cross section from its interference with the Bethe-Heitler amplitude. This provides a stronger way to constrain the Generalized Parton Distributions of the nucleon. A wide range of kinematics accessible with an 11 GeV beam off an unpolarized proton target will be covered. The Q(2)-dependence of each contribution will be measured independently.
