dc.description.abstract We present a detailed analysis of S-wave K pi scattering up to 2 GeV, making use of the resonance chiral Lagrangian predictions together with a suitable unitarisation method. Our approach incorporates known theoretical constraints at low and high energies. The present experimental status, with partly conflicting data from different experiments, is discussed. Our analysis allows to resolve some experimental ambiguities, but better data are needed in order to determine the cross-section in the higher-energy range, Our best fits are used to determine the masses and widths of the relevant scalar resonances in this energy region.
