    "abstract": "Two-nucleon effective field theory (EFT) beyond momenta of order the pion\nmass is studied for both cutoff regularization and dimensional regularization\nwith power divergence subtraction (PDS). Models with two mass scales illustrate\nhow effects of long-distance pion physics must be removed from the coefficients\nthat encode short-distance physics. The modified effective range expansion\nshows that treating pions perturbatively, as in the PDS power counting, limits\nthe radius of convergence of the EFT. Predictions from both regularization\nschemes with one-pion contributions are compared to data. The breakdown of the\neffective field theory occurs for momenta of order 300 MeV, even using the\nmodified effective range expansion. This behavior is shown to be consistent\nwith that expected from two-pion contributions.",
