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…
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…
Covariant Level-Classification Scheme and Chiral Symmetry
Shin Ishida, Muneyuki Ishida, Tomohito Maeda
Starting from the bi-local Klein-Gordon Equation with spin-independent squared-mass operator, we give a covariant quark representation of general composite meson systems with defin…
