    "abstract": "Nonperturbative effective field theory calculations for NN scattering seem to\nbreak down at rather low momenta. By examining several toy models, we clarify\nhow effective field theory expansions can in general be used to properly\nseparate long- and short-range effects. We find that one-pion exchange has a\nlarge effect on the scattering phase shift near poles in the amplitude, but\notherwise can be treated perturbatively. Analysis of a toy model that\nreproduces 1S0 NN scattering data rather well suggests that failures of\neffective field theories for momenta above the pion mass can be due to\nshort-range physics rather than the treatment of pion exchange. We discuss the\nimplications this has for extending the applicability of effective field\ntheories.",
