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.

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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
