Bootstrap equations for effective theories and the calculation of the $G_T/G_V$ ratio

Abstract

A method is described for dealing with effective theories of hadron scattering. It allows one to reduce the number of independent renormalization prescriptions in those theories and gives a possibility to make numerical predictions. As an illustration, we show the results of comparison with the known data on $\pi \pi$, $\pi K$ and $\pi N$ elastic scattering. This work presents a generalization and the further development of our results first discussed at the MENU'99 Symposium
