Binding energies versus proton radii. The results for a 14C and b 15C are shown. The coloured bands and red-horizontal lines are the experimental values. The green band represents the proton radius from the electron scattering. The filled black symbols are the CC predictions with SRG-evolved NN + 3NF chiral effective interactions at different NN/3NF cutoffs and NNLOsat, whereas the open symbols are the predictions with the NN-only EM and NNLOsat interactions. The error bars are the estimated theoretical uncertainties due to truncations of the employed method and model space53. See text for details
