Double Counting Ambiguities in the Linear Sigma Model
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.Comment: 23 pages To be published in Journal of Physics
