OBSERVATION OF HARD SCATTERING IN PHOTOPRODUCTION AT HERA

OBSERVATION OF HARD SCATTERING IN PHOTOPRODUCTION AT HERA

We report a study of electron proton collisions at very low Q2, corresponding to virtual photoproduction at centre of mass energies in the range 100-295 GeV. The distribution in transverse energy of the observed hadrons is much harder than can be explained by soft processes. Some of the events show...
