• 論文の詳細を見る

• Recently we have given evidence for the existence of the σ particle. In these previous works, the ππ S-wave phase shift is reanalyzed, by introducing a repulsive background suggested by the chiral symmetry, and by applying the new method of Interfering Breit-Wigner amplitudes. In this work we also show, reanalyzing the Kπ S-wave phase shift from a similar standpoint, evidence for the possible existence of κ(900), to be assigned as a member of the σ nonet.
