- Descrição
- We compare, in kaon-pion scattering, chiral perturbation method and the unitarization program of current algebra. As occured in pion-pion, we show in this paper that, even having different number of free parameters, both methods lead to the same analytic structure for the amplitudes. The main difference between the two approaches resides in phase-shift definition. We reproduce in this paper a three parameter fit of experimental <math>K \pi</math> S and P phase- shifts of the quasi-unitarized amplitude.
