An Analysis of ππ-Scattering Phase Shift and Existence of σ(555) particle
S. Ishida, M. Y. Ishida, H. Takahashi +3
In most of the Nambu:Jona-Lasinio(NJL)-type models, realizing the hidden chiral symmetry, the existence of a scalar particle σis needed with a mass m_σ=2 m_q, as a partner of the N…

Further Analysis on σ-particle Properties
Shin Ishida, Taku Ishida, Muneyuki Ishida +2
In a previous work, we have reanalyzed the I=0 S-wave ππ-scattering phase-shift through a new method of Interfering Breit-Wigner amplitudes, and have shown the existence of a light…
