A bb b b di-bottomonium at the LHC?
Abstract
We study the case of a di-bottomonium bb b b 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 bb b b tetraquark is expected approximately 100 MeV below threshold, and compare to a recent analysis by LHCb seeking it in the μμ final state.
