/ Abstract
We present a calculation of the scattering phase shift for the I = 2 S-wave pion-pion system in the continuum limit with two-flavor full QCD. Calculations are made at three lattice spacings, using the finite volume method of Luscher in the center of mass frame, and its extension to the laboratory frame.
