Chiral gauge theories and anomalies in the Wilson renormalization group approach
Abstract
We extend the Wilson renormalization group (RG) formulation to chiral gauge theories and show that local gauge symmetry can be implemented by a suitable choice of the RG flow boundary conditions. Since the spacetime dimension is four, there is no ambiguity in handling the matrix γ _{5} and left and right fermions are not coupled. As a result, the ultraviolet action contains all possible globally chiral invariant interactions. Nevertheless, the correct chiral anomaly is reproduced.
