Abstract
I present the results of a recent calculation to determine the number of strange scalar resonances below 1.8 GeV based on the analytic properties of the experimental pi K scattering amplitude. Only one resonance was found in the data, and this is readily identifiable as the K_0^*(1430). We found no evidence to support the kappa(900).
