Abstract
We show that it is necessary to go beyond a single hadron (beyond the quark-antiquark or three-quark systems) in order to distinguish the colour structure of the effective quark-quark interaction and the relevance of 3-body forces. We critically discuss the proposed models which suggest the dimeson bb\bar{u}\bar{d} to be bound by ~ 100 MeV and the cc\bar{u}\bar{d} dimeson to be unbound. Only experiment can judge. We estimate the probability of producing bb-\bar{u}\bar{d} at LHC by double gluon-gluon fusion and search for a characteristic decay.
