Hyperon I: Partial-wave amplitudes for K-p scattering
. Early data on K - induced reactions off protons are collected and used in a coupled-channel partial-wave analysis (PWA). Data that had been published in the form of Legendre coefficients are included in the PWA. In a primary fit using 3 * and 4 * resonances only, we observe some significant discre...

Early data on

induced reactions off protons are collected and used in a coupled-channel partial-wave analysis (PWA). Data that had been published in the form of Legendre coefficients are included in the PWA. In a
primary
fit using

resonances only, we observe some significant discrepancies with the data. In a systematic search for new

hyperon resonances, additional candidates are found. The significance of the known and of the additional resonances is evaluated. Seventeen resonances listed with
