Making chiral fermion actions (almost) gauge invariant using Laplacian gauge fixing
Jeroen C. Vink
Abstract
Straight foreward lattice descriptions of chiral fermions lead to actions that break gauge invariance. I describe a method to make such actions gauge invariant (up to global gauge transformations) with the aid of gauge fixing. To make this prescription unambiguous, Laplacian gauge fixing is used, which is free from Gribov ambiguities.
