A study of quark-gluon vertices using the lattice Coulomb gauge domain wall fermion (original) (raw)

This study examines the quark-gluon vertices using lattice simulations with Domain Wall Fermion (DWF) configurations under the Coulomb gauge. It presents a non-perturbative method for extracting running couplings and investigates the infrared properties of the running coupling in relation to previous results derived from Landau gauge. The findings suggest that the infrared behavior of the couplings differs significantly between the two gauges, raising questions about confinement criteria and highlighting future research directions in DWF simulations.
