Jet Cross Sections in gamma*-gamma Scattering at e+e- Colliders in NLO QCD
B. Pötter
Abstract
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 Q2 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 Weizs"acker-Williams approximation. Four components of the cross sections have to be distinguished, involving direct and resolved real and virtual photon contributions. Since Q2 is non-zero, the virtual photon structure function is needed to calculate the contributions involving a resolved virtual photon.
