A New Perspective on Chiral Gauge Theories

Many different approaches have been pursued in the attempt to define chiral gauge theories on the lattice, all of which either break gauge symmetry explicitly, or are procedures for eliminating unwanted mirror fermions from the theory. I discuss a recently published proposal that combines domain wall fermions with gradient flow as a new idea for how to decouple the mirror fermions, which leads us to a chiral overlap operator.
