Colour Coherence in Photon Induced Reactions
A. Lebedev, L. Sinclair, E. Strickland +1
Colour coherence in hard photoproduction is considered using the Monte Carlo event generators PYTHIA and HERWIG. Significant effects in the parton shower are found using multijet o…

Rapidity Gaps Between Jets
J. M. Butterworth, M. E. Hayes, M. H. Seymour +1
An excess of events with a rapidity gap between jets, over what would be expected from non-diffractive processes, has been observed at HERA. A process based on a perturbative QCD c…

Rapidity Gaps in Hard Photoproduction
L. E. Sinclair
Recent results obtained from studies of diffractive processes in hard photoproduction performed by the ZEUS collaboration using data delivered by HERA in 1993 and 1994 are presente…
