Query: I=2 pion-pion scattering phase shift in the continuum limit calculated
  with two-flavor full QCD   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 L\"uscher
in the center of mass frame, and its extension to the laboratory frame.
