I=2 Pion Scattering Phase Shift with Wilson Fermions

Abstract

We present results of phase shift for I=2 $S$-wave $\pi \pi$ system with the Wilson fermions in the quenched approximation. The finite size method proposed by Lüscher is employed, and calculations are carried out at $\beta =5.9$ ($a^{-1}=1.934(16)$ GeV from $m_{\rho }$) on $24^3\times 60$, $32^3\times 60$, and $48^3\times 60$ lattices.
