Abstract

The structure functions of real and virtual photons are derived from cross section measurements of the reaction e⁺e^-→e⁺e^-+ hadrons at LEP. The reaction is studied at √s≃ 91 GeV with the L3 detector. One of the final state electrons is detected at a large angle relative to the beam direction, leading to Q² values between 40 GeV² and 500 GeV². The other final state electron is either undetected or it is detected at a four-momentum transfer squared P² between 1 GeV² and 8 GeV². These measurements are compared with predictions of the Quark Parton Model and other QCD based models.
