pi^0 pi^0 Scattering Amplitudes and Phase Shifts Obtained by the pi^- P Charge Exchange Process
Kunio Takamatsu
The results of the analysis of the pi^0 pi^0 scattering amplitudes obtained with pi^- P charge exchange reaction, pi^- P --> pi^0 pi^0 n, data at 9 GeV/c are presented. The pi^0 pi…
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…
Weak Radiative Decay Lambda_b to Lambda gamma and Quark-Confined Effects in the Covariant Oscillator Quark Model
Rukmani Mohanta, Anjan K. Giri, Mohinder P. Khanna +2
Motivated by the observation of the decay B to K* gamma by the CLEO collaboration, we have systematically analyzed the weak radiative decay Lambda_b to Lambda gamma, evaluating the…
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…
Controversies on and a Reasoning for Existence of the light sigma-particle
Shin Ishida
The light sigma-particle is, regardless of the strong criticism, reviving recently due to the works done from various sides. I review essential points of the controversies (especia…
Covariant Classification of q q bar-Meson Systems and Existence of New Scalar and Axial-Vector Mesons
Shin Ishida, Muneyuki Ishida
The level classification of quark-antiquark systems is generally made by the LS-coupling scheme, resorting to the non-relativistic quark model. However, it has been well known that…
Exclusive Weak Radiative Decays of B Mesons in the Covariant Oscillator Quark Model
Rukmani Mohanta, Anjan K. Giri, Mohinder P. Khanna +2
Exclusive weak radiative B meson decays are studied using the covariant oscillator quark model. The branching ratios for the processes B0 to K*0 gamma and B to K* gamma have been e…
Hadronic Weak Decays of Lambda b Baryon in the Covariant Oscillator Quark Model
Rukmani Mohanta, Anjan K. Giri, Mohinder P. Khanna +3
Cabibbo allowed two-body hadronic weak decays of Lambda b baryons are analyzed in the factorization approximation. We use the covariant oscillator quark model to evaluate the heavy…
Non-leptonic Two-meson Decays of B-Mesons in the Covariant Oscillator Quark Model with Factorization Ansatz
Rukmani Mohanta, Anjan K. Giri, Mohinder P. Khanna +3
Exclusive nonleptonic bottom meson decays are studied in the covariant osillator quark model using the factorization assumption. The main feature of this model is that it can simul…
