Properties of single cluster structure of $d^*(2380)$ in chiral SU(3) quark modelMar 11 2016Jun 16 2016The structure of $d^*(2380)$ is re-studied with the single cluster structure in the chiral SU(3) quark model which has successfully been employed to explain the scattering and binding behaviors of baryonic systems. The mass and width are explicitly calculated ... More
Six-quark structure of $d^*(2380)$ in chiral constituent quark modelApr 27 2017The structure of $d^*(2380)$ is re-studied with the single cluster structure in the chiral SU(3) quark model which has successfully been employed to explain the $N-N$ scattering data and the binding energy of deuteron. The binding behavior of such a six ... More
