Description

The processes γγ->μ+μ-e+e- and γγ->e+e-e+e- with polarized photons are studied in detail. They are the most suitable processes for determining the luminosity of high-energy γγ colliding beams. Completely differential, inclusive and total cross sections as well as energy spectra are calculated. All the distributions depend only on the linear photon polarizations. In the single muon inclusive cross section polarization effects may reach 19%. The application of our results to QCD multi-jet production in γγ collisions is briefly discussed. (orig.)
