We study the case of a di-bottomonium bbb¯ b¯ particle at the LHC. Its mass and decay width are obtained within a new model of diquark–antidiquark interactions in tetraquarks.

Abstract
We study the case of a di-bottomonium bbb¯ 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 bbb¯ b¯ tetraquark is expected approximately 100 MeV below threshold, and compare to a recent analysis by LHCb seeking it in the Υ μμ final state.| File | Dimensione | Formato | |
