Renormalization of chiral nuclear forces with multiple subtractions in peripheral channels
arXiv:1702.06312 · doi:10.1155/2017/2316247
Abstract
We analyse the renormalization of the of two-nucleon interaction with multiple subtractions in peripheral waves considering two chiral forces at N3LO. Phase shifts at low energies are then computed with several subtraction points below μ= 10 / fm. We show that for most peripheral waves the phase shifts have nearly no dependence on the renormalization scale. In two cases the phase shifts converge slowly as the renormalization scale approaches μ= 1 / fm and in one case the phase shifts presented oscillations with respect to the subtraction point μ.
