Resolved Photon Processes
Manuel Drees, Rohini M. Godbole
Abstract
We review high--energy scattering processes that are sensitive to the hadronic structure of the photon, describing theoretical predictions as well as recent experimental results. These processes include deep--inelastic electron--photon scattering at \ colliders; and the production of jets, heavy quarks and isolated photons in the collision of real photons at \ colliders, as well as in photon--proton collisions at ep colliders. We also comment on ``minijet'' based calculations of total γp and \ cross--sections, and discuss the possibility that future linear \ colliders might produce very large photon fluxes due to the ``beamstrahlung'' phenomenon; in the most extreme cases, we predict more than one hadronic \ event to occur at every bunch crossing.
