Lattice regularized chiral perturbation theory

Abstract

Chiral perturbation theory can be defined and regularized on a spacetime lattice. A few motivations are discussed here, and an explicit lattice Lagrangian is reviewed. A particular aspect of the connection between lattice chiral perturbation theory and lattice QCD is explored through a study of the Wess-Zumino-Witten term.Comment: 7 pages, 1 figure, presented at the Workshop on Lattice Hadron Physics (LHP2003), Cairns, Australi
