abstract
The calculation of the I=2 pion scattering length in quenched lattice QCD is reexamined. The calculation is carried out with the Wilson fermion action employing Lüscher's finite size scaling method at β=5.9, 6.1, and 6.3 corresponding to the range of lattice spacing a≃0.12-0.07 fm. We obtain in the continuum limit a0/mπ=-2.09(35) 1/GeV2, which is consistent with the prediction of chiral perturbation theory a0/mπ=-2.265(51)1/GeV2.
