Four Quark cn - nbar cbar States in U(12)-Scheme and X(3872)/Y(3940)
Muneyuki Ishida, Shin Ishida, Tomohito Maeda
The properties of four quark cn - nbar cbar states are investigated as cn di-quark and nbar cbar di-antiquark system in U(12)-classification scheme of hadrons, recently proposed by…
The DsJ*(2317) and DsJ(2460) mesons in U~(12)-classification scheme of hadrons
Shin Ishida, Muneyuki Ishida, Tomohito Maeda +2
The narrow mesons, DsJ*(2317) and DsJ(2460), observed recently in the final states Ds+ pi0 and Ds*+ pi0 are pointed out to be naturally assigned as the ground-state scalar and axia…
Ground State Baryons in Covariant Level-Classification Scheme
Muneyuki Ishida, Shin Ishida
In the covariant level-classification scheme of hadrons based on U(12)SF * O(3,1)L symmetry, the ground state baryons and antibaryons are assigned to the (12 * 12 * 12)Sym = 364-mu…
Relation between Scattering and Production Amplitudes -- Case of sigma and kappa in pipi and Kpi Systems --
Muneyuki Ishida, Shin Ishida
In our talk at Nihon university symposium, we have argued that the pipi / Kpi production amplitudes F generally have different structures from those of the pipi / Kpi scattering am…
Properties of sigma and kappa Production Amplitudes
Muneyuki Ishida, Shin Ishida
Our method of analysis, which led to existence of sigma and kappa mesons, is reviewed and examined from a viewpoint of general S-matrix. It is shown that the method is consistent w…
Covariant Classification Scheme of Hadrons and Chiral States
Shin Ishida, Muneyuki Ishida
The essential points and physical backgrounds of the covariant level-classification scheme, recently proposed by us, are reviewed: In this scheme the general composite hadrons are…
