摘要
We present results for I = 2 pion scattering length with the Wilson fermions in the quenched approximation. The finite size method presented by Luscher is employed, and calculations are carried out at beta = 5.9, 6.1, and 6.3. In the continuum limit, we obtain a result in reasonable agreement with the experimental value.
