Soft and hard photoproduction news from H1 at HERA

Abstract

This report presents some preliminary results from measurements of photoproduction events collected with the H1 detector at the HERA ep colliding storage rings. The results concern the total gamma p cross section, diffractive vector meson production, inclusive particle and jet production, and the partonic content of the photon. Some conclusions on hard parton processes and on their interplay with soft physics are discussed. The data were taken during the autumn of 1992. They correspond to an integrated luminosity of 21.9+or-1.5 nb-1.
