Rigorous QCD-Potential for the -System at Threshold
W. Kummer, W. Moedritsch
Recent evidence for the top mass in the region of 160 for the first time provides an opportunity to use the full power of relativistic quantum field theoretical methods, avai…

Gauge-Independent Bound-State Corrections to the Toponium Decay Width
W. Moedritsch, W. Kummer
Off-shell and relativistic bound-state corrections for the decay are calculated to $O(\a_s^2)$ making full use of the Bethe-Salpeter formalism for weakly bound systems.…
