Abstract
We compare two different frameworks which have been proposed to include the
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.
