Abstract
Chiral gauge groups acting on a lattice fermion field are constructed such that all fermion modes (doublers) have the same charge. Details are given for an abelian axial gauge group within a perturbative framework. An action based on this group correctly reproduces the continuum gauge-current anomaly, while preserving global chiral symmetry, locality, rotational symmetry and hermiticity. A Wess-Zumino-like scalar field enters naturally to enforce exact chiral gauge invariance. The degeneracy amongst the doublers can be lifted as in a vector model.
