摘要：

We present a lattice gauge-fixing action S-gf with the following properties: (a) S-gf is proportional to the trace of (Sigma(mu)partial derivative(mu)A(mu))(2), plus irrelevant terms of dimension six and higher; (b) S-gf has a unique absolute minimum at U-x,U-mu = I. Noting that the gauge-fixed action is not BRST invariant on the lattice, we discuss some important aspects of the phase diagram. (C) 1997 Published by Elsevier Science B.V.
