Abstract
We study the dynamical consequences imposed on effective chiral field theories such as the quark-level SU(2) linear model (LM) due to the fundamental constraints of massless Goldstone pions, the normalization of the pion decay constant and form factor, and the pion charge radius. We discuss quark-level double counting LM ambiguities in the context of the Salam-Weinberg compositeness condition. Then SU(3) extensions to the kaon are briefly considered.
