Large $N$ Weinberg-Tomozawa interaction and spin-flavor symmetry

High Energy Physics - Phenomenology 2008-11-26 v1

Abstract

The construction of an extended version of the Weinberg-Tomozawa Lagrangian, in which baryons and mesons form spin-flavor multiplets, is reviewed and some of its properties discussed, for an arbitrary number of colors and flavors. The coefficient tables of spin-flavor irreducible representations related by crossing between the ss-, tt- and uu-channels are explicitly constructed.
