Confinement and bound states in QCD
G. M. Prosperi
I revue the so called Wilson loop approach to bound state problem in QCD. I shall show how using appropriate path integral representations for the quark propagator in an external f…
Quark-antiquark Bethe-Salpeter formalism, spectrum and Regge Trajectories
G. M. Prosperi
Starting from a path integral representation of appropriate 4-point and 2-point gauge invariant Green functions and from the "Modified Area Law" model for the evaluation of the Wil…
First principle qqbar Salpeter equation, spectrum and Regge trajectories
M. Baldicchi, G. M. Prosperi
Starting from a first principle Salpeter equation we computed the heavy-heavy, light-light and heavy-light quarkonium spectrum and the ground light-light Regge trajectories. We neg…
Schwinger-Dyson Equation, Area Law and Chiral Symmetry in QCD
G. M. Prosperi
A Schwinger-Dyson equation for the quark propagator is derived in the context of a Bethe-Salpeter second order formalism developped in preceding papers and of the Minimal Area Law…
Quark--Antiquark Bethe--Salpeter Equation in QCD
N. Brambilla, G. M. Prosperi
We review our recent results \cite{bsult} on the derivation of a B-S equation in QCD in a Wilson loop context. We work in a second order formalism, use the Feynman--Schwinger path…
