12 Jacek Dobaczewski EFT phase-shift analysis np phase parameters below 300 MeV lab. energy for partial waves with J=0,1,2. The solid line is the result at N 3 LO. The dotted and dashed lines are the phase shifts at NLO and NNLO, respectively, as obtained by Epelbaum et al. The solid dots show the Nijmegen multi-energy np phase shift analysis and the open circles are the VPI single-energy np analysis SM99. D.R. Entem and R. MachleidtPhys.Rev. C68 (2003)
