Coulomb-gauge gluon propagator and the Gribov formula.
We analyze the lattice SU(2) Yang-Mills theory in the Coulomb gauge. We show that the static gluon propagator is multiplicative renormalizable and takes the simple form D(|p[over -->]|)(-1)=sqrt[|p[over -->]|2+M4/|p[over -->]|2], proposed by Gribov through heuristic arguments many years ago. We find M=0.88(1) GeV approximately 2sqrt[sigma].
