A $bb\bar b\bar b$ di-bottomonium at the LHC?

TL;DR

This paper investigates the properties of a di-bottomonium tetraquark at the LHC, predicting its mass and decay width using a new diquark-antidiquark interaction model, and compares predictions with experimental searches.

Contribution

Introduces a novel diquark-antidiquark interaction model that explains tetraquark phenomenology and predicts a $bbar bar b$ state approximately 100 MeV below threshold.

Findings

Predicted mass of the $bbar bar b$ tetraquark is about 100 MeV below threshold.

Model successfully addresses open problems in $X,Z$ state phenomenology.

Comparison with LHCb analysis suggests experimental search strategies.

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.
