【 摘 要 】

The Real Compton Scattering experiment was performed in all A at the Thomas Jefferson National Accelerator Facility. It was designed to measure, for Compton scattering and π 0 -photoproduction, the differential cross section over a range of kinematic points and the polarisation transfer to the proton at a single kinematic point. The full range of the experiment in Mandelstam variables t and s was 1.64−6.46 GeV 2 and 4.82−10.92 GeV 2 respectively with beam energies of 2−6 GeV. The motivation for the experiment is to test the cross section and polarisation trans-fer predictions of perturbative QCD versus that of predictions from Generalised Parton Distribution models. This thesis will give an overview of the pertinent theory, experimental setup in Hall A and the extracting of the π 0 -photoproduction cross section.
