Abstract：
After summarizing the experimental results and present status of the d ^*(2380) observed at WASA@COSY, two "extreme" models for explaining its structure, a compact hexaquark dominated model and a loose △△'- D ₁₂π model, are briefly discussed, especially the former. By comparing their results with the corresponding data, the differences of the two models are addressed. As a remedy for the latter model, a mixing model and its result are also quoted for a comparison. It is shown that the compact hexaquark dominated structure might be more promising. However, the mixing model is also a possible structure, and more accurate Γ _d^*→NNπdata are needed for confirmation.
- d*(2380),
- chiral quark model,
- strong pionic decays
