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…

Hexaquark picture for d*(2380)

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

$d^\ast(2380)$ was observed by WASA-at-COSY collaborations in the nuclear reaction recently. Its particularly narrow width may indicate the new QCD-allowed hadronic structure. To further confirm the

$$d^*(2380)$$d∗(2380) and its partners in a diquark model

The purpose of the present study was to explore the possibility of accommodating the $$d^*(2380)$$d∗(2380) and its flavor SU(3) partners in a diquark model. Proposing that $$d^*(2380)$$d∗(2380) is

Isotensor Dibaryon in the pp→ppπ^{+}π^{-} Reaction?

TLDR
Calculations describing these excitations by t-channel meson exchange are at variance with the measured differential cross sections and underpredict substantially the experimental total cross section.

Resonance d*(2380) and higher isospin states

A new isoscalar state in the two-baryon system with mass 2380 MeV and width 80 MeV denoted now d*(2380) has been detected in the experiments at the Juelich Cooler Synchrotron (COSY). Existence or

Pion production in nucleon-nucleon collisions and the issue of dibaryons

Pion production in nucleon-nucleon collisions is tightly connected with the issue of dibaryons. After having established the existence of the narrow dibaryon resonance d* (2380) with I(JP) = 0(3+) by

Dibaryons: Molecular versus compact hexaquarks

Hexaquarks constitute a natural extension of complex quark systems, just as tetra- and pentaquarks do. To this end, the current status of in both experiment and theory is reviewed. Recent

In this work, we study the doubly charmed dibaryon states with the qqqqcc ( q = u, d, s ) configuration. The mass spectra of doubly charmed dibaryon states are obtained systemically within the

We confirm our previous prediction of a $d^*$ state with $I(J^P)=0(3^+)$ [Phys. Rev. C 60, 045203 (1999)] and report for the first time based on a microscopic calculation that $d^*$ is a hexaquark

TLDR
A modification of the resonating-group method (RGM) is proposed which includes the multiquark shell-model configurations in the nucleon overlap region, which enables one to cover a wide interval of {ital NN} scattering energies up to {ital E}{sub lab}=2 GeV.
