Species Doubling and Chiral Lagrangians
arXiv:hep-ph/9605322 · doi:10.1103/PhysRevLett.76.4671
Abstract
Coupling gauge fields to the chiral currents from an effective Lagrangian for pseudoscalar mesons naturally gives rise to a species doubling phenomenon similar to that seen with fermionic fields in lattice gauge theory.
