The Pomeron in Exclusive $J/\ddot{I}ˆ$ Vector Meson Production

Abstract

An earlier developed model for vector meson photoproduction, based on a dipole Pomeron exchange, is extended to electroproduction. Universality of the non linear Pomeron trajectory is tested by fitting the model to ZEUS and H1 data as well as to CDF data on $\bar{p}p$ elastic scattering
