| We develop a subtractive renormalization scheme to evaluate the NN scattering phase shifts using chiral effective theory potentials. This allows us to consider arbitrarily high cutoffs in the Lippmann-Schwinger equation. We employ NN potentials computed up to next-to-next-to-leading order (NNLO) in chiral effective theory, using both dimensional regularization and spectral-function regularization. We evaluate the cutoff-dependence and the renormalization point dependence of our results, and apply them to the calculation of the process of deuteron electro-disintegration. |
