OBSERVATION OF DIRECT PROCESSES IN PHOTOPRODUCTION AT HERA

Jets in photoproduction events have been studied with the ZEUS detector for γp centre-of-mass energies ranging from 130 to 250 GeV. The inclusive jet distributions give evidence for the dominance of resolved photon interactions. In the di-jet sample the direct processes are for the first time clearl...
