Ananthanarayan, B and Büttiker, P (2001) Comparison of Pion-Kaon Scattering in SU(3) Chiral Perturbation Theory and Dispersion Relations. [Preprint]
We establish the framework for the comparison of $\pi K$ scattering amplitudes from SU(3) chiral perturbation theory with suitable dispersive representations which result from the combination of certain fixed-t dispersion relations with dispersion relations on hyperbolic curves. This allows for predictions for some combinations of low energy constants appearing in higher order calculations of chiral perturbation theory. Using a simple parametrization for the lowest partial waves, first estimates for some combinations are presented.
