Deep inelastic compton-scattering with polarized beam and target

Abstract

The helicity difference of the photon photoproduction process γp→γx is calculated using four different polarized proton structure functions. Also discussed are the contributions originating from the Compton cross-section and the subprocesses of\(\mathcal{O}(\alpha \alpha _s )\) induced by photon structure and fragmentation. Up-quark and gluondominance can be separated by choosing different regions of pseudorapidity η and normalized transverse momentumX′ T of the final-state photon. We show, that it is possible to distinguish between the two extreme models of proton spin: polarized gluon vice polarized strange-quark.
