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^…
On the running coupling constant in QCD
G. M. Prosperi, M. Raciti, C. Simolo
We try to review the main current ideas and points of view on the running coupling constant in QCD. We begin by recalling briefly the classic analysis based on the Renormalization…
Running coupling constant and masses in QCD, the meson spectrum
M. Baldicchi, G. M. Prosperi
In line with some previous works, we study in this paper the meson spectrum in the framework of a second order quark-antiquark Bethe-Salpeter formalism which includes confinement.…
Light mesons and infrared behavior of the running coupling constant in QCD
M. Baldicchi, G. M. Prosperi
A previous method for handling bound states in QCD is briefly revisited. Taking advantage of the Feynman-Schwinger representation for the iterated quark propagator in an external f…
Infrared behavior of the running coupling constant and quarkonium spectrum
M. Baldicchi, G. M. Prosperi
We study the effect of the infrared behavior of the running coupling constant on the quark-antiquark spectrum.
