Using three different interpolating operators for Θ, we measure the 3×3 correlation matrix and obtain the eigenvalues A±(t) with ± parity for 100 gauge configurations generated with Wilson gauge action at β=6.1 on the 203×40 lattice. For the lowest-lying JP=1/2- state, its mass is almost identical to that of the KN s wave, while for the lowest-lying JP=1/2+ state, its mass is smaller than that of the KN p wave, especially for the regime mu |
