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 $0\ensuremath{\hbar… 7 Citations ## Figures from this paper Hexaquark picture for d*(2380) • Physics • 2020 Hexaquark wave function with the quantum numbers$I({J}^{P})=0({3}^{+})$, which might be relevant for${d}^{*}(2380)$, is constructed under an assumption that this is composed only of$u$,$d$quarks Contribution of the vector meson to the ϒ(nS)→d¯*(2380)+X decay channel • Physics Physical Review D • 2019$d^\ast(2380)$was observed by WASA-at-COSY collaborations in the nuclear reaction recently.
