Chiral fermions from lattice boundaries
Abstract
We construct a model in which fourdimensional chiral fermions arise on the boundaries of a fivedimensional lattice with free boundary conditions in the fifth direction. The physical content is similar to Kaplan's model domain wall fermions, yet the present construction has several technical advantages. We discuss some aspects of perturbation theory, as well as possible applications of the model both for lattice QCD and for the ongoing attempts to construct a lattice chiral gauge theory.
