Effect of light sigma-meson Production in ppbar --> 3 pi0 at rest
Muneyuki Ishida, Toshihiko Komada, Shin Ishida +3
The pi0 pi0 mass spectra and angular distributions around KKbar -threshold and at 1.5 GeV in ppbar (at rest) --> 3 pi0 in the Crystal Barrel experiment are reanalyzed by applying t…
Effect of sigma(600)-Production in pp_bar to 3pi0 at rest
Muneyuki Ishida, Toshihiko Komada, Shin Ishida +3
The pi0 pi0 mass spectra and angular distributions around KK_bar-threshold and at 1.5 GeV in pp_bar(at rest) to 3pi0 in the Crystal Barrel experiment are reanalyzed by applying the…
Relation between Scattering and Production Amplitudes - concerning sigma Particle in pi pi System -
Muneyuki Ishida, Shin Ishida, Taku Ishida
In a series of previous papers the present authors and collaborators have shown strong evidence for existence of the long-sought sigma-particle by analyzing the pi pi-scattering an…
Reply to the criticism raised by Pennington on our pipi-Production Amplitudes
Muneyuki Ishida, Shin Ishida, Taku Ishida
A recent criticism raised by M.R.Pennington on our pipi-production amplitudes seems to be due to his misunderstanding on our description, and is not right. Essential point of the r…
Relation between Scattering and Production Amplitude - Case of Intermediate σ-Particle in ππ-System
Muneyuki Ishida, Shin Ishida, Taku Ishida
The relation between scattering and production amplitudes are investigated, using a simple field theoretical model, from the general viewpoint of unitarity and the applicability of…
σ-Particle in Production Processes
Kunio Takamatsu, Muneyuki Ishida, Shin Ishida +2
A S-wave ππresonance below 1 GeV/c^2, sigma has been observed in analyses of the phase shift data of ππscatterings. It is important to observe it in production processes. A huge ev…
