Abstract: (Elsevier)

We introduce a new stochastic regularization for continuum gauge theory. The scheme is a covariant derivative regularization of the Parisi-Wu Langevin equation, or equivalently, the Schwinger-Dyson equations. The regularized formulation is manifestly Lorentz invariant, gauge-invariant, ghost-free and finite to all orders. We verify a vanishing gluon mass at one loop.
