    "abstract": "We discuss convergence issues as well as short distance constraints on the\ndeuteron wave functions based on chiral perturbation theory relevant to pion\ndeuteron scattering. Non-analytical terms arise in the multiple scattering\nseries for the pion-deuteron scattering length limiting the accuracy of the\ncalculations. This result resembles similar findings in the structure of the NN\ninteraction. The effects are found not to be numerically large. The iso-scalar\n$\\pi N $ scattering length from the iso-vector one and the $\\pi d$ scattering\nlength yields values compatible with the experimental number and with much\nsmaller errors.",
