We study the dynamical consequences imposed on effective chiral field theories such as the quark-level SU (2) linear σ model (LσM) 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 LσM ambiguities in the context of the Salam-Weinberg Z = 0 compositeness condition. SU (3) extensions to the kaon are then briefly considered.
