abstract

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

Discussion (0). Continue with ORCID to comment.

    hep-ph 2019-08 conditional novelty 5.0 of 10

    For fully-heavy bbcc and bcbc tetraquarks, the chiral quark model finds no bound states but predicts several resonances above the two-meson thresholds.
