Query: Minimally non-local nucleon-nucleon potentials with chiral two-pion
  exchange including $\Delta$'s   We construct a coordinate-space chiral potential, including $\Delta$-isobar
intermediate states in its two-pion-exchange component. The contact
interactions entering at next-to-leading and next-to-next-to-next-to-leading
orders ($Q^2$ and $Q^4$, respectively, $Q$ denoting generically the low
momentum scale) are rearranged by Fierz transformations to yield terms at most
quadratic in the relative momentum operator of the two nucleons. The low-energy
constants multiplying these contact interactions are fitted to the 2013 Granada
database, consisting of 2309 $pp$ and 2982 $np$ data (including, respectively,
148 and 218 normalizations) in the laboratory-energy range 0--300 MeV. For the
total 5291 $pp$ and $np$ data in this range, we obtain a $\chi^2$/datum of
roughly 1.3 for a set of three models characterized by long- and short-range
cutoffs, $R_{\rm L}$ and $R_{\rm S}$ respectively, ranging from $(R_{\rm
L},R_{\rm S})=(1.2,0.8)$ fm down to $(0.8,0.6)$ fm. The long-range
(short-range) cutoff regularizes the one- and two-pion exchange (contact) part
of the potential.
