Description

A simple explanation is given for the forward peaking observed in proton Compton scattering cross sections at photon energies above 800 MeV, in a nonrelativistic constituent quark model of the scattering process using intermediate resonances. This represents an alternate explanation to that using the standard vector-dominance model. Cross sections at these energies are calculated in a specific model, and the results compare favorably with the data, but the mechanism for forward peaking can be explained on rather general grounds
