2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/111246We propose a construction of a 2-dimensional lattice chiral gauge theory. The construction may be viewed as a particular limit of an infinite warped 3-dimensional theory. We also present a "single-site'' construction using Ginsparg-Wilson fermions which may avoid, in both 2 and 4 dimensions, the problems of waveguide-Yukawa models.16 pages, 5 figures, comments and references added, published versionHigh Energy Physics - LatticeHigh Energy Physics - Theorytext
