New developments in multi-meson systems

Abstract

New developments in the study of multi-meson systems are reviewed. We highlight a new recursive algorithm for generating the requisite contractions needed for studying complex systems of mesons involving large numbers of particles or multiple species of particles. First results on mixed species systems involving pions and kaons are also presented.
