The data are compatible with the Coulomb-only interaction hypothesis within $(1.1-1.5)\\sigma$.Considering an attractive nucleon(N)$\\overline{\\mathrm{D}}$ strong interaction, in contrast to most model predictions which suggest an overall repulsive interaction, slightly improves the level of agreement.
