The η′ and the topological charge density

Abstract

We compare two different frameworks which have been proposed to include the eta' in chiral perturbation theory. The equivalence of these two approaches is shown both for the purely mesonic case and in the presence of the ground state baryon octet. The relation between the different sets of parameters in both Lagrangians is clarified.
