The two-particle momentum correlations of pD(-) and (p) over barD(+) pairs are measured by the ALICE Collaboration in high-multiplicity pp collisions at root s = 13 TeV. The data are compatible with the Coulomb-only interaction hypothesis within (1.1-1.5)sigma. The level of agreement slightly improves if an attractive nucleon (N)(D) over bar strong interaction is considered, in contrast to most model predictions which suggest an overall repulsive interaction. This measurement allows for the first time an estimation of the 68% confidence level interval for the isospin I = 0 inverse scattering length of the N (D) over bar state f(0,I=0)(-1) is an element of[-0.4, 0.9] fm(-1), assuming negligible interaction for the isospin I = 1 channel.
