A clear test of perturbative QCD in large-p/sub T/ photoproduction

It is shown that measurement of the cross-section differences Ed sigma /d/sup 3/p( gamma p to h/sup +/X)-Ed sigma /d/sup 3/p( gamma p to h /sup -/X) at large transverse momentum provides a good test of perturbative QCD. Such differences are insensitive to the parton Fermi motion and to the poorly kn...

description It is shown that measurement of the cross-section differences Ed sigma /d/sup 3/p( gamma p to h/sup +/X)-Ed sigma /d/sup 3/p( gamma p to h /sup -/X) at large transverse momentum provides a good test of perturbative QCD. Such differences are insensitive to the parton Fermi motion and to the poorly known sea-quark and gluon distribution functions. Moreover the hadronized photon component is shown to contribute little compared to the point-like one. Presently available photon beams at the CERN-SPS and FNAL are sufficient to test QCD in large-p/sub T/ photoproduction. (15 refs).
