High Energy Photon Colliders. *
Using the laser backscattering method at future linear colliders one can obtain γγ and γe colliding beams (photon colliders) with energy and luminosity comparable to that in ee collisions. This option has been included in the pre-conceptual designs of linear colliders and in work on a Technical Design Report which is in progress. The physics motivation for photon colliders is quite clear. The p...
متن کاملPhysics at High Energy Photon Photon Colliders
I review the physics prospects for high energy photon photon colliders, emphasizing results presented at the LBL Gamma Gamma Collider Workshop. Advantages and difficulties are reported for studies of QCD, the electroweak gauge sector, supersymmetry, and electroweak symmetry breaking. This work was supported by the Director, Office of Energy Research, Office of High Energy and Nuclear Physics, D...
متن کاملProduction of a High Energy , High Power Polarized Photon Beam at Siac
Attenuation by coherent pair production in highly oriented compression annealed pyrolytic graphite has been used to polarize a 16 GeV bremsstrahlung beam. Graphite pieces of total volume 0.95 X 0.95 X 5.1 cm3 were assembled in watercooled precision holders. Eighteen of these units were mounted in two independent coaxial assemblies. Each assembly provided precision angular orientation with respe...
متن کاملHigh Energy Beam-beam Effects in Clic
In order to achieve high luminosity, the Compact Linear Collider (CLIC) has to be operated in the highbeamstrahlung regime at centre-of-mass energies in the few TeV range. Beam-beam effects for this case are simulated. The dependence of luminosity, luminosity spectrum and background conditions on the different beam parameters is investigated. In particular the effect of beam size, waist shift a...
متن کاملHigh Energy Photon-photon and Electron-photon Collisions *
The advent of a next linear e ± e − collider and back-scatterd laser beams will allow the study of a vast array of high energy processes of the Standard Model through the fusion of real and virtual photons and other gauge bosons. As examples, I discuss virtual photon scattering γ * γ * → X in the region dominated by BFKL hard Pomeron exchange and report the predicted cross sections at present a...
