摘要：
A coordinate-space nucleon-nucleon potential is constructed in chiral effective field theory (chi EFT) retaining pions, nucleons and Delta-isobars as explicit degrees of freedom. The calculation of the potential is carried out by including one-and two-pion-exchange contributions up to next-to-next-to-leading order (N2LO) and contact interactions up to next-to-next-to-next-to-leading order (N3LO). The low-energy constants multiplying these contact interactions are fitted to the 2013 Granada database in the laboratory-energy range 0-300 MeV.
