%0 Journal Article %T Photon Structure %A J. Turnau %J Physics %D 2001 %I arXiv %X Measurements of di-jet production at HERA provide an important test of NLO QCD calculations. It is also a source of information about partonic content of the photon, complementary to the measurements in e+e- experiments. In this article we review the status of the photon structutre studies with particular emphasis on HERA measurements. %U http://arxiv.org/abs/hep-ex/0102019v1
