Unitarity, Chiral Perturbation Theory, and Meson Form Factors
The inverse-amplitude method is applied to the one-loop chiral expansion of
the pion, kaon, and form factors. Since these form factors are
determined by the same chiral low-energy constants, it is possible to obtain
finite predictions for the inverse-amplitude method. It is shown that this
method clearly improves one-loop chiral perturbation theory, and a very good
agreement between the inverse-amplitude method and the experimental information
is obtained. This suggests that the inverse-amplitude method is a rather
systematic way of improving chiral perturbation theory.Comment: 15 pages, 5 figs, uses REVTeX and epsfig.st
