We study the case of a di-bottomonium particle at the LHC. Its mass and decay width are obtained within a new model of diquark–antidiquark interactions in tetraquarks. The same model solves several open problems on the phenomenology of the experimentally better known X, Z states. We show that the 
tetraquark is expected approximately 100 MeV below threshold, and compare to a recent analysis by LHCb seeking it in the 
final state.
