Fully-heavy hexaquark states via the QCD sum rules

TL;DR

This paper uses QCD sum rules to predict the masses of fully-heavy hexaquark states, providing theoretical guidance for future experimental searches in invariant mass spectra.

Contribution

It introduces a new method to construct vector six-quark currents for fully-heavy hexaquarks and predicts their masses, extending previous work on heavy multiquark states.

Findings

Predicted masses of fully-heavy hexaquark states.

Suggested experimental search channels in di-Ω_ccc and di-Ω_bbb spectra.

Connected results with previous tetraquark and pentaquark studies.

Abstract

We construct the diquark-diquark-diquark type vector six-quark currents to investigate the vector and scalar hexaquark states in the framework of the QCD sum rules in a consistent way, and make predictions for the hexaquark masses. We can search for the fully-heavy hexaquark states in the di-$ \Omega_{ccc}$ and di-$ \Omega_{bbb}$ invariant mass spectra in the future. Combined with our previous works on the fully-heavy tetraquark states and pentaquark states, the present predictions can shed light on the nature of the fully-heavy multiquark states.
