We study the case of a di-bottomonium bbbˉbˉ 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 bbbˉbˉ tetraquark is expected approximately 100 MeV below threshold, and compare to a recent analysis by LHCb seeking it in the Υμμ final state.
