✦ Synopsis

The double dissociation photoproduction cross section for the process 7P -+ XY, in which the systems X and Y are separated by a large rapidity gap, is measured at large 4-momentum transfer squared [t I > 20GeV 2 by the H1 Collaboration at HERA. This measurement provides for the first time a direct measurement of the energy dependence of the gap production process at high It].
