Heavy Quark Masses from Sum Rules in Four-Loop Approximation
Johann H. Kuehn, Matthias Steinhauser, Christian Sturm
New data for the total cross section in the charm and bottom threshold region are combined with an improved theoretical analysis, which includes recent four…
Radiative return at e+e- factories
H. Czyz, J. H. Kuehn, G. Rodrigo
The energy dependence of the electron - positron hadronic cross section can be measured not only by a straightforward energy scan, but also by means of the radiative return method.…
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…
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…
Theoretical Aspects of Decays
J. H. Kuehn, E. Mirkes, J. Willibald
Predictions based on the chirally normalized vector meson dominance model for decay rates and distributions of decays into final states are discussed. Disagreements wi…
