    "abstract": "We study the two-nucleon force at next-to-next-to-leading order in a chiral\neffective field theory with explicit Delta degrees of freedom. Fixing the\nappearing low-energy constants from a next-to-leading order calculation of\npion-nucleon threshold parameters, we find an improved convergence of most\nperipheral nucleon-nucleon phases compared to the theory with pions and\nnucleons only. In the delta-full theory, the next-to-leading order corrections\nare dominant in most partial waves considered.",
