Photoproduction of events with rapidity gaps between jets at HERA
- Abstract:
- The photoproduction of dijet events, where the two jets with the highest transverse energy are separated by a large gap in pseudorapidity, have been studied with the ZEUS detector using an integrated luminosity of 39 pb−1. Rapiditygap events are defined in terms of the energy flow between the jets, such that the total summed transverse energy in this region is less than some value E^CUT T. The data show a clear excess over the predictions of standard photoproduction models. This is interpreted as evidence for a strongly interacting exchange of a color-singlet object. Monte Carlo models which include such a color-singlet exchange are able to describe the data.
