Abstract
We propose to use the High Momentum Spectrometer of Hall C combined with a PbWO₄ electromagnetic calorimeter in order to perform high precision measurements of the Deeply Virtual Compton Scattering (DVCS) cross section. A wide range of kinematics accessible with an 11 GeV electron beam off an unpolarized proton target will be covered. The azimuthal, energy and helicity dependences of the cross section will all be exploited in order to separate the interference and DVCS² contributions to each of the Fourier moments of the cross section. For each term, its Q² dependence will be measured independently. At the same time, the exclusive π⁰ electroproduction cross section will also be measured and a longitudinal/transverse separation will be performed. The total request is for 65 days of beam.
