I=2 Pion Scattering Length with Wilson Fermions
Abstract
We present results for I=2 pion scattering length with the Wilson fermions in the quenched approximation. The finite size method presented by L\"uscher is employed, and calculations are carried out at β=5.9, 6.1, and 6.3. In the continuum limit, we obtain a result in reasonable agreement with the experimental value.
