Low-lying $s=+1$ Pentaquark states in the Inherent Nodal Structure Analysis

The strangeness $s=+1$ pentaquark states as $qqqq\bar{q}$ clusters are investigated in this letter. Starting from the inherent geometric symmetry, we analyzed the inherent nodal structure of the system. As the nodeless states, the low-lying states are picked out. Then the S-wave state $(J^P, T)= ({1/2}^{-}, 0)$ and P-wave state $(J^P, T)= ({1/2}^{+}, 0)$ may be the candidates of low-lying pentaquark states. By comparing the accessibility of the two states and referring the presently obtained K-N interaction potential, we propose that the quantum numbers of the observed pentaquark state $Θ^{+}$ may be $(J^P, T)=({1/2}^{+}, 0)$ and L=1.

Low-lying S-wave and P-wave Dibaryons in a Nodal Structure Analysis

The dibaryon states as six-quark clusters of exotic QCD states are investigated in this paper. With the inherent nodal surface structure analysis, the wave functions of the six-quark clusters (in another word, the dibaryons) are classified. The contribution of the hidden color channels are discussed. The quantum numbers of the low-lying dibaryon states are obtained. The States $[ΩΩ]_{(0,0^{+})}$, $[ΩΩ]_{(0,2^{-})}$, $[Ξ^{*}Ω]_{(1/2,0^{+})}$, $[Σ^{*}Σ^{*}]_{(0,4^{-})}$ and the hidden color channel states with the same quantum numbers are proposed to be the candidates of dibaryons, which may be observed in experiments.

Low-lying States of $^{6}$He and $^{6}$Be in Nodal Surface Structure Analysis

The low-lying states of light nuclei $^6$He and $^6$Be are studied. Using the inherent nodal surface(INS) analysis approach, we deduce the quantum numbers and the spatial symmetries of the low-lying states with positive parity and negative parity of the two nuclei. The energy spectrum obtained agrees well with the experimental data.
