Lattice QCD and Chiral Lagrangians

Abstract

After a very brief review of the formalism of lattice gauge theories we show how one can calculate the parameters of the continuum chiral Lagrangians proceeding through the derivation of an effective lattice chiral Lagrangian as an intermediary step. The derivation is done in the strong coupling limit. We also discuss how the derivation could be carried out in the intermediate coupling domain by numerical simulation techniques. Based on a lecture given by C. Rebbi at the 1993 ICTP Summer School in High Energy Physics and Cosmology, to be published in the proceedings of the School (World Scientific Publishing - Singapore - 1994.)
