Possible Evidence for a Chiral Axial-Vector State in the D Meson System
Kenji Yamada, Muneyuki Ishida, Shin Ishida +3
We reanalyze the D^{*+} pi^- mass spectrum from CLEO II by the VMW method in order to examine the existence of a chiral axial-vector state, which is predicted in a covariant level-…
Property of Chiral Scalar and Axial-Vector Mesons in Heavy-Light Quark Systems
Muneyuki Ishida, Shin Ishida
Recently we have proposed a new level-classification scheme of hadrons with a manifestly covariant framework. In this scheme the requirement of chiral symmetry on the light quark l…
Covariant Classification Scheme of Hadrons
Shin Ishida, Muneyuki Ishida
Starting from the multi-local Klein-Gordon equations with Lorentz-scalar squared-mass operator we give a covariant quark representation of the general composite mesons and baryons…
Confirmation of sigma(450--600)-Meson in Upsilon' to Upsilon pipi and Other pipi-Production Processes
Muneyuki Ishida, Shin Ishida, Toshihiko Komada +1
Applying the effective amplitude, which is evidently consistent with general constraints from chiral symmetry, the pipi spectra in the relevant processes are analyzed, leading to a…
The sigma-Meson Production in Excited Upsilon Decay Processes
Toshihiko Komada, Muneyuki Ishida, Shin Ishida
We analyze the pipi production amplitudes in the excited Upsilon decay processes, Upsilon (2S) to Upsilon (1S)pi^+pi^-, Upsilon (3S) to Upsilon (1S)pi^+pi^- and Upsilon (3S) to Ups…
Property of Chiral Scalar and Axial-Vector Mesons in Heavy-Light Quark System
Muneyuki Ishida, Shin Ishida
We investigate the properties of new scalar X_B, X_D and axial-vector X_B*, X_D* mesons, which are recently predicted, in the covariant meson-classification scheme, to exist as the…
