Six-quark structure of d * ( 2380 ) in a chiral constituent quark model
@article{Lu2017SixquarkSO, title={Six-quark structure of d * ( 2380 ) in a chiral constituent quark model}, author={Qi-Fang Lu and Fei Huang and Yubing Dong and Peng-nian Shen and Zong Ye Zhang}, journal={Physical Review D}, year={2017}, volume={96}, pages={014036} }
The structure of ${d}^{*}(2380)$ is restudied with the single cluster structure in the chiral SU(3) quark model which has successfully been employed to explain the $N\ensuremath{-}N$ scattering data and the binding energy of deuteron. The binding behavior of such a six quark system is solved by using a variational method. The trial wave function is chosen to be a combination of a basic spherical symmetric component of $[(0s{)}^{6}{]}_{\mathrm{orb}}$ in the orbital space with $0\ensuremath{\hbar…
