| Abstract: | We study the restrictions imposed on chiral symmetry breaking terms by a set of postulates, whose main content is furnished by certain ideas of Michel and Radicati. We then test certain particular cases by utilizing an effective Lagrangian and calculating meson-meson scattering lengths. A convenient technique for calculating traces of matrices which appear in our model is presented in an appendix. |
