摘要
The structure of real and virtual photons has been studied in ep collisions at HERA using dijet production. Measurements of differential dijet cross sections as function of the fraction of photon's momentum invested in the dijet system are presented. The dependence of the cross sections on the virtuality of the photon and mean transverse energy squared of the two leading jets has been investigated. QCD calculations based on current parametrizations of the real and virtual photon parton distribution functions have been compared to the data.
