Stochastic vacuum model and dual theory: a comparison in the context of the heavy quarkonia potential
N. Brambilla, A. Vairo
The semirelativistic interaction in QCD can be expressed in terms of the Wilson loop and its functional derivatives. In this framework we discuss the complete (velocity…

Gauge invariance on bound state energy levels
A. Vairo
In this paper the problem of the gauge in a bound state calculation is discussed. In particular, in order to verify the gauge invariance in the energy levels expansion, some set of…
