Resumo

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 fm(-1) and 1 fm(-1). In this range, the results are scale invariant and provide an overall good agreement with the Nijmegen partial wave analysis up to at least E-lab = 150 MeV, with a cutoff at Lambda = 30 fm(-1). (AU)
