Top production above threshold: Electroweak and QCD corrections combined
J. Kuehn, T. Hahn, R. Harlander
Top quark production in electron-positron annihilation is one of the benchmark reactions at a future linear collider. Both electroweak and QCD corrections are large, amounting to 1…
Quark mass effects to σ(e^+e^- -> hadrons) at O(α_s^3)
K. G. Chetyrkin, R. Harlander, J. H. Kuehn
The calculation of the quartic mass terms at order α_s^3 to the hadronic R ratio is described. It is based on the operator product expansion for the quark current correlator, combi…
Measuring sigma(e^+e^- \to hadrons) using tagged photon
S. Binner, J. H. Kuehn, K. Melnikov
We propose to use events with radiated photons in e^+e^- collisions to measure the total cross section of e^+ e^- \to hadrons as a function of the center of mass energy. The Monte…
Expansion Techniques in Massive Quark Production: Results and Applications
J. H. Kuehn
Recent progress in the calculation of multi-loop, multi-scale diagrams is reviewed. Expansion techniques combined with new developments in Computer algebra allow to evaluate the R…
