QCD coupling below 1 GeV from quarkonium spectrum
M. Baldicchi, A. V. Nesterenko, G. M. Prosperi +1
In this paper we extend the work synthetically presented in Ref.[1] and give theoretical details and complete tables of numerical results. We exploit calculations within a Bethe-Sa…
Bound state approach to the QCD coupling at low energy scales
M. Baldicchi, A. V. Nesterenko, G. M. Prosperi +2
We exploit theoretical results on the meson spectrum within the framework of a Bethe-Salpeter (BS) formalism adjusted for QCD, in order to extract an ``experimental'' coupling α_s^…
A Dual Gauge Model with Confinement
G. A. Kozlov, M. Baldicchi
We reformulate the dual gauge model of the long-distance Yang-Mills theory in terms of the two-point Wightman functions formalism. In the flux-tube scheme of Abelian dominance and…
First principle quadratic and linear mass operators, quarkonium spectrum and Regge trajectories
M. Baldicchi
In previous works, a squared mass operator M^2 and a more common centre of frame Hamiltonian H_CM for the quark-antiquark system were obtained by using the only assumption that ln…
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…
