    "abstract": "An analytic expression for the ${}^1S_0$ phase shifts in nucleon-nucleon\nscattering is derived in the context of the Schr\\\"odinger equation in\nconfiguration space with a short distance cutoff and with a consistent power\ncounting scheme including pionic effects. The scheme treats the pion mass and\nthe inverse scattering length over the intrinsic short distance scale as small\nparameters. Working at next-to-leading order in this scheme, we show that the\nexpression obtained is identical to one obtained using the recently introduced\nPDS approach which is based on dimensional regularization with a novel\nsubtraction scheme. This strongly supports the conjecture that the schemes are\nequivalent provided one works to the same order in the power counting.",
