Subtractive renormalization of the NN interaction in chiral effective theory up to next-to-next-to-leading order: S waves

C. -J. Yang, Ch. Elster, D. R. Phillips

We extend our subtractive-renormalization method in order to evaluate the 1S0 and 3S1-3D1 NN scattering phase shifts up to next-to-next-to-leading order (NNLO) in chiral effective…
