Strong coupling constant from the 1-loop improved static energy
Viljami Leino, Alexei Bazavov, Nora Brambilla +8
The static energy is an excellent observable for extracting the strong coupling on the lattice. For short distances, the static energy can be calculated both on the lattice u…
Schwinger Model with a Dynamical Axion
Gabriel Rouxinol, Tom Magorsch, Jesse J. Osborne +2
One of the major open puzzles in the Standard Model of particle physics is the strong CP problem: although Quantum Chromodynamics allows a CP-violating topological -term, experi…
Field Strength Correlators and Dual Effective Dynamics in QCD
M. Baker, N. Brambilla, H. G. Dosch +1
We establish a relation between the two-point field strength correlator in QCD and the dual field propagator of an effective dual Abelian Higgs model describing the infrared behavi…
Nonperturbative evaluation of a field correlator appearing in the heavy quarkonium system
M. Baker, J. S. Ball, N. Brambilla +1
Recently an electric and magnetic field correlator appearing in the description of the heavy quarkonium system was evaluated on the lattice. Here, we give a nonperturbative analyti…
Confinement: Understanding the Relation Between the Wilson Loop and Dual Theories of Long Distance Yang Mills Theory
M. Baker, J. S. Ball, N. Brambilla +2
In this paper we express the velocity dependent, spin dependent heavy quark potential in QCD in terms of a Wilson Loop determined by pure Yang Mills theory. We…
Three-body relativistic flux tube model from QCD Wilson-loop approach
N. Brambilla, G. M. Prosperi, A. Vairo
First we review the derivation of the relativistic flux tube model for a quark-antiquark system from Wilson area law as we have given in a preceding paper. Then we extend the metho…
Confining Bethe--Salpeter equation in QCD
N. Brambilla, G. M. Prosperi
We derive a confining Bethe--Salpeter equation starting from the same assumptions on the Wilson loop integral already adopted in the derivation of a semirelativistic h…
Bethe--Salpeter equation in QCD
N. Brambilla, E. Montaldi, G. M. Prosperi
We extend to regular QCD the derivation of a confining Bethe--Salpeter equation previously given for the simplest model of scalar QCD in which quarks are treated as sp…
A consistent derivation of the quark--antiquark and three quark potentials in a Wilson loop context
N. Brambilla, P. Consoli, G. M. Prosperi
In this paper we give a new derivation of the quark-antiquark potential in the Wilson loop context. This makes more explicit the approximations involved and enables an immediate ex…
