    "abstract": "Nogga, Timmermans and van Kolck recently argued that Weinberg\u0027s power\ncounting in the few-nucleon sector is inconsistent and requires modifications.\nTheir argument is based on the observed cutoff dependence of the\nnucleon-nucleon scattering amplitude calculated by solving the\nLippmann-Schwinger equation with the regularized one-pion exchange potential\nand the cutoff Lambda varied in the range Lambda = 2...20 fm^(-1). In this\npaper we discuss the role the cutoff plays in the application of chiral\neffective field theory to the two-nucleon system and study carefully the\ncutoff-dependence of phase shifts and observables based on the one-pion\nexchange potential. We show that (i) there is no need to use the momentum-space\ncutoff larger than Lambda ~ 3 fm^(-1); (ii) the neutron-proton low-energy data\nshow no evidence for an inconsistency of Weinberg\u0027s power counting if one uses\nLambda ~ 3 fm^{-1}.",
