Direct and resolved pomeron

Abstract

We investigate the effect of a direct pomeron coupling to quarks in DIS and photoproduction of jets. The direct pomeron coupling generates a point-like contribution to the diffractive part of the structure function $F_2$, which is analysed on the basis of the latest H1 data. Our model assumptions for the pomeron structure are consistent with the measured data.
