Asymptotic constraint for chiral condensation of Coulomb gauge QCD

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

We study the3 P 0 quark-antiquark pair condensation in QCD, representing the gluon-interaction approximately by instantaneous Coulomb plus Breit potential. Particular attention is paid to non-uniqueness of the solution of the gap equation. The genuine dynamical solution can be characterized by a rapidly convergent behavior at large momentum, as was recognized in covariant formulations of Landau gauge. We impose the required behavior and make a numerical study of the chiral condensation.
