摘要：

We investigate a new lattice regularization of gauge theories where gauge invariance with noncompact gauge fields is realized with the help of auxiliary fields. For the gauge group SU(2) there is only one auxiliary field. We construct the complete action for scaling dimension 2 of this field. In this case the regularization amounts to relaxing the unitarity of the Wilson link variables, but has the same renormalization scale parameter showing the stability of Wilson's fixed point.
