Peripheral NN scattering from subtractive renormalization of chiral interactions

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 $0.1{\mathrm{fm}}^{-1}$ and $1{\mathrm{fm}}^{-1}$. In this range, the results are scale invariant and provide an overall goof agreement with the Nijmegen partial wave analysis up to at least $E_{\mathrm{lab}}=150\mathrm{MeV}$, with a cutoff at $\Lambda =30{\mathrm{fm}}^{-1}$.
