Title: Fixed-point Interactions And Renormalization Group Invariance In The Two-nucleon System
Author: Timoteo V.S.

Abstract: We study the fixed-point interactions and the renormalization group invariance for an effective nucleonnucleon (NN) interaction in the leading-order (LO) chiral effective field theory (ChEFT) renormalized within the framework of the subtracted kernel method (SKM) approach. By solving a nonrelativistic CallanSymanzik (NRCS) equation we show how the driving term evolves with the subtraction scale to keep the T-matrix invariant. We calculate the fixed-point interaction from the driving term and compare the results obtained with and without its evolution through the NRCS equation. © 2010 World Scientific Publishing Company.
