AbstractAbstract

[en] 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 Luescher is employed, and calculations are carried out at β = 5.9 on a 24³ x 60 and 32³ x 60 lattice
