Production of 3pi0 and eta 2pi0 from pi-p Collision in GAMS Experiment
Masaaki Kobayashi, Tsuneaki Tsuru, Kunio Takamatsu +4
The data on the pi- p --> M0 n, with M0 = pi0 pi0 pi0 or pi0 pi0 eta obtained in the GAMS experiment may be useful to study the sigma(400--700) and a_1^chi (1000), which can be tak…
sigma and kappa in Scattering Processes and New pi0 pi0 Phase Shift Data
Kunio Takamatsu
The evidences for sigma(600) and kappa(900) observed in our analyses on the pi pi and K pi scattering phase shift data are described, briefly. The analysis have been performed by t…
pi0 pi0 Scattering Amplitudes in the pi- p Charge Exchange Process and pi0 pi0 Phase Shift Analysis
Kunio Takamatsu
The amplitude analysis has been performed on the pi0 pi0 final state obtained in the pi- p charge exchange process. The pi0 pi0 scattering amplitudes have been obtained for the S a…
Observed Properties of sigma-particle
Muneyuki Ishida, Shin Ishida, Taku Ishida +2
Recently we obtained the evidence for the existence of sigma(600) meson, which had been sought but missing for a long time, by reanalyzing the I=0 S-wave pi pi scattering phase shi…
