Title: Power Counting And Renormalization Group Invariance In The Subtracted Kernel Method For The Two-nucleon System
Author: Szpigel S.
Timoteo V.S.
Abstract: We apply the subtracted kernel method (SKM), a renormalization approach based on recursive multiple subtractions performed in the kernel of the scattering equation, to the chiral nucleon-nucleon (NN) interactions up to nextto- next-to-leading-order.We evaluate the phase-shifts in the 1S 0 channel at each order in Weinberg's power counting scheme and in a modified power counting scheme which yields a systematic power-law improvement. We also explicitly demonstrate that the SKM procedure is renormalization group invariant under the change of the subtraction scale through a non-relativistic Callan-Symanzik flow equation for the evolution of the renormalized NN interactions. © 2012 IOP Publishing Ltd.
