The Unintegrated Gluon Density in the Photon and Heavy Quark Production

High Energy Physics - Phenomenology 2007-05-23 v2

Abstract

The production cross section of heavy quarks in real and virtual photon-photon collisions has been studied. The unintegrated gluon density in the photon was obtained using the full CCFM evolution equation for the first time. The gluon density was implemented in the Monte Carlo generator CASCADE, and cross sections for heavy quark production in e+ee^+e^- collisions were calculated and compared to LEP data. Also, predictions for heavy quark cross sections in e+ee^+e^- and γγ\gamma\gamma collisions at TESLA energies are given.
