    "abstract": "Based on a recent manifestly covariant time-ordered approach to the\nrelativistic many-body problem, the quark propagator is defined by a nonlinear\nDyson--Schwinger-type integral equation, with a one-gluon loop. The resulting\nenergy-dependent quark mass is such that the propagator is singularity-free for\nreal energies, thus ensuring confinement. The self-energy integral converges\nwithout regularization, due to the chiral limit of the quark mass itself.\nMoreover, the integral determines the low-energy limit of the quark-gluon\ncoupling constant, for which a value of $g^2/4\\pi =4.712$ is found.",
