We study the case of a di-bottomonium $$bb\bar{b}$$$$\bar{b}$$ par-ticle 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 $$bb\bar{b}$$$$\bar{b}$$ tetraquark is expected approximately 100 MeV below threshold, and compare to a recent analysis by LHCb seeking it in the Yμμ final state.
