25 Dec 2003 | | Subject: | hep-ph | | Abstract: | The strangeness $s=+1$ pentaquark states as $qqqqar{q}$ 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 $Theta^{+}$ may be $(J^P, T)=({{1/2}}^{+}, 0)$ and L=1. | | Source: | arXiv, hep-ph/0401197 | | Services: | Forum | Review | PDF | Favorites | |
