A bb(b)over-bar(b)over-bar di-bottomonium at the LHC?

Abstract

We study the case of a di-bottomonium bb (b) over bar(b) over bar 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) over bar(b) over bar tetraquark is expected approximately 100 MeV below threshold, and compare to a recent analysis by LHCb seeking it in the Y mu mu final state.
