Measurement of Elastic ˚Photoproduction at HERA ZEUS Collaboration Abstract The production of ˚mesons in the reaction e+p!e+˚p(˚!K+K−)atamedian Q2of 10−4 GeV2 has been studied with the ZEUS detector at HERA. The di erential ˚ photoproduction cross section d˙=dthas an exponential shape and has been determined. Recent experimental results from HERA on inclusive diffractive scattering, exclusive vector meson production and the properties of the hadronic final state in diffraction are reviewed. The results are discussed in the context of current theoretical models.

Dijet Photoproduction at HERA and the structure of the Photon DESY ; J.C,;: hep-ex/ Spires: Thesis: UCL J M Butterworth. For the 2-jet cross section we demonstrate the cancellation of infrared, collinear and rapidity singularities. Our result can bedirectly exploited to describe the recently analyzed data on exclusive dijet production at HERA and used for the study of jet photoproduction in ultraperipheral proton or nuclear scattering.

Subject: Experimental High Energy Physics: Organization: Experimental High Energy Physics: Journal title:Cited by: Photo-Excited Processes, Diagnostics and Applications covers the area of photo-excitation and processing of materials by photons from the basic principles and theories to applications, from IR to x-rays, from gas phase to liquid and solid phases. The various chapters give a wide spectral view of this developing field. Twelve leading groups worldwide set down to write this book during the past Manufacturer: Springer.

More recently, diffractive deep-inelastic scattering (DDIS) processes at HERA [6, 7], of the type ep →eXp, have been studied in detail and have led to a new level of understanding of the properties and structure of the diffractive exchange.
