Abstract

The strangeness s=+1 pentaquark states and the six-quark quark clusters qqqqqq are investigated. By analyzing the inherent nodal structure of the systems, the low-lying states are picked out. By comparing the accessibility of the nodeless states and referring the presently obtained K-N interaction potential, we propose that the quantum numbers of the lowest-lying pentaquark state Θ⁺ may be (J^P, T)=(½⁺,0) and L=1. Meanwhile, the possible dibaryon states are briefly discussed.
