We have used perturbative QCD to calculate the complete set of helicity amplitudes for the real and virtual Compton-scattering reactions (*)pp, using a variety of wave functions. A particularly interesting feature of these results is the existence of nontrivial phases in the amplitudes, and a great deal of structure in the amplitudes as a function of the virtuality of the initial photon. Results for s6 d/dt(pp) are compared to existing data.
