June 1993 Amsterdam ITFA 93-13 UCSD / PTH 93-13 Staggered fermions for chiral gauge theories : Test on a two-dimensional axial-vector model

As a first step towards constructing chiral models on the lattice with staggered fermions, we study a U(1) model with axial-vector coupling to an external gauge field in two dimensions. In our approach gauge invariance is broken, but it is restored in the classical continuum limit. We find that the continuum divergence relations for the vector and… CONTINUE READING
