Abstract

We determine the two loop correction to Gribov's mass gap equation for quantum chromodynamics in the Landau gauge in the MS̄ scheme by computing the two loop correction to the horizon condition derived from Zwanziger's local renormalizable Lagrangian which incorporates the Gribov parameter. We verify that with the explicit result, the two loop ghost propagator is enhanced in the infrared. © 2005 Elsevier B.V. All rights reserved.
