Peripheral NN scattering from subtractive renormalization of chiral interactions

Nuclear Theory 2014-12-08 v2

Abstract

We apply five subtractions in the Lippman-Schwinger (LS) equation in order to perform a non-perturbative renormalization of chiral N3LO nucleon-nucleon interactions. Here we compute the phase shifts for the uncoupled peripheral waves at renormalization scales between 0.1 fm10.1~ \rm{fm}^{-1} and 1 fm11 ~ \rm{fm}^{-1}. In this range, the results are scale invariant and provide an overall goof agreement with the Nijmegen partial wave analysis up to at least Elab=150 MeVE_{\rm{lab}} = 150 ~ \rm{MeV}, with a cutoff at Λ=30 fm1\Lambda = 30~\rm{fm}^{-1}.
