Weak Coupling Limit and Genuine QCD Predictions for Heavy Quarkonia
W. Kummer, W. Moedritsch
Although individual levels of toponium will be unobservable, the top--anti--top system near threshold fulfills all requirements of a rigorous perturbation theory in QCD for weakly…

Toponium as Nonabelian Positronium ?
W. Kummer, W. Mödritsch
The expected large mass of the top quark provides for the first time a chance to discuss the bound-states of the corresponding quantum system as the nonabelian generalization…
