摘要：
Recent results from NLO QCD calculations for inclusive jet cross sections in gamma*gamma-scattering at e(+)e(-) colliders, especially for LEP, are reported. The virtuality Q(2) of the virtual photon is non-zero and can be unlimited large. The virtuality of the second photon is zero and the spectrum is calculated with the Weizsacker-Williams approximation. Four components of the cross sections have to be distinguished, involving direct and resolved real and virtual photon contributions. Since Q(2) is non-zero, the virtual photon structure function is needed to calculate the contributions involving a resolved virtual photon.
