Hard Photoproduction and the Structure of the Photon
Laurel Sinclair
A pedagogical introduction to the experimental results on hard photoproduction at HERA is provided. Then the latest results in this field from ZEUS and H1 are reviewed.
Jets and Prompt Photons in Photoproduction at ZEUS
L. E. Sinclair
In the ZEUS experiment at HERA, photoproduction processes have been studied for photon-proton centre-of-mass energies in the range 100 < W_gamma p < 300 GeV and jet transverse ener…
Dynamics of Multijet Processes in Photoproduction
L. E. Sinclair
The cross section for producing three high transverse energy jets with a three-jet invariant mass of M_3J > 50 GeV has been measured in photoproduction at HERA. The angular distrib…
Recent Results from the study of QCD and Jets at HERA
Laurel E. Sinclair
The HERA experiments H1 and ZEUS have recently presented a number of interesting results from studies of the hadronic final state produced in collisions. These studies have fo…
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…
