We perform a study of the ND̅ interaction within a chiral constituent quark model. This model has been completely tight in the description of the NN interaction and the baryon and meson spectra, therefore provides a parameter–free framework from where to address the problem of the charm − 1 two hadron systems. We predict the existence of a unique bound state, ΔD̅ with (T,S) = (1,5/2), that would appear in the scattering of FX3 mesons on nucleons as a D̅ wave state. This resonance resembles our findings in the ΔΔ system, that offered a plausible explanation to the cross section of double–pionic fusion reactions through the so–called ABC effect.
