We examine the two solutions (massive and scaling) for the covariant Yang–Mills Dyson–Schwinger equations within stochastic quantization, and find that the scaling solution does not survive outside Landau gauge. We also see that the (rainbow) massive solution has less Faddeev–Popov effective action. Finally, we argue that gluon confinement has only been marginally established in experiment and suggest further empirical work.
