A [Formula: see text] di-bottomonium at the LHC?

We study the case of a di-bottomonium [Formula: see text] 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....

Sumario:We study the case of a di-bottomonium [Formula: see text] 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 [Formula: see text] tetraquark is expected approximately 100 MeV below threshold, and compare to a recent analysis by LHCb seeking it in the [Formula: see text] final state.
