Experimental Indication of Existence of Extra Light-Vector Mesons omega'(1.3) and rho'(1.3)
Toshihiko Komada
Mass distributions of pi^+ pi^- pi^0 and omega pi^0 systems in the e^+ e^- annihilation obtained by the several experiments are analyzed. We obtain indication of light-vector meson…
Possible Evidence for a Chiral Particle B_0chi, Scalar Meson in the B Meson System
Daiki Ito, Muneyuki Ishida, Shin Ishida +3
In the covariant level-classification scheme of hadrons proposed recently, the existence of "chiral particles", scalar and axial-vector mesons as the partners of the ground-state p…
Possible Evidence for a Chiral Particle D_1chi, Axial-Vector in the D Meson System
Daiki Ito, Muneyuki Ishida, Shin Ishida +3
In the covariant level-classification scheme of hadrons proposed recently, the existence of "chiral particles", scalar and axial-vector mesons as the partners of the ground-state p…
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…
Light sigma-Meson Production in Excited Upsilon Decay Processes II: Theoretical Investigation
Muneyuki Ishida, Shin Ishida, Toshihiko Komada
The results of analyses obtained in Part I are examined from the viewpoint of chiral symmetry. The mass spectra of pi pi system are widely believed to be suppressed generally near…
