I=2 Pion Scattering Length and Phase Shift with Wilson Fermions
Abstract
We present preliminary results of scattering length and phase shift for I=2 S-wave ππ system 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 on a 243× 60 and 323× 60 lattice.
