Abstract

We calculate the Faddeev-Popov operator corresponding to the maximally Abelian gauge for gauge group SU(N). Specializing to SU(2) we look for explicit zero modes of this operator. Within an illuminating toy model (Yang-Millsmechanics) the problem can be completely solved and understood. In the held theory case we are able to find an analytic expression for a normalizablezero mode in the background of a single 't Hooft instanton. Accordingly, such an instanton corresponds to a horizon configuration in the maximally Abelian gauge. Possible physical implications are discussed. (C) 2000 Elsevier Science B.V.
