This is called photon structure. Electron-positron collisions at LEP are an ideal laboratory for studying photon structure and for testing QCD.10 pages, 7 figures, uses sprocl.sty, submitted to proceedings of Lake Louise Winter Institute, Canada, Feb. 15-21, 1998High Energy Physics - Experimenttext
