dc.descriptionRecently we have shown an evidence for existence of σ-particle in the previous works; where the ππS-wave phase shift is reanalyzed, by introducing a repulsive background suggested by the chiral symmetry, and by applying a new method of Interfering Breit-Wigner Amplitudes. In this work we also show, reanalyzing the KπS-wave phase shift from a similar standpoint, an evidence for existence of κ(900), possibly to be a member of σ-nonet.
