Axial symmetries in lattice QCD with Kaplan fermions
Abstract
A lattice definition of QCD based on chiral defect fermions is discussed in detail. This formulation involves (infinitely) many heavy regulator fields, realized through the introduction of an unphysical fifth dimension. It is proved that nonsinglet axial symmetries become exact in the limit of an infinite fifth dimension, and before the continuum limit is taken.
