dc.description.abstract | We investigate the mass spectrum of the pentaquark baryon (ududs̄) in quenched lattice QCD with exact chiral symmetry. 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<ms. By chiral extrapolation (linear in mπ2) to mπ=135MeV, we obtain the masses of the lowest-lying states: m(1/2-)=1424(57)MeV and m(1/2+)=1562(121)MeV, in agreement with the masses of mK+mN 1430MeV and Θ+(1540), respectively. © 2005 The American Physical Society. | - |
