I=2 Pion Scattering Length with Wilson Fermions

Abstract: We present results for the I=2 pion scattering length with the Wilson fermions. High statistics calculations are carried out in the quenched approximation at $\beta=6.0$ and $6.3$. We investigate the problem of chiral logarithms by comparing our results with the prediction of quenched chiral perturbation theory. We also discuss chiral symmetry breaking effect of the Wilson fermions.
