Contribution

It introduces a novel application of flux-tube configurations and potential models to predict tetraquark masses, advancing understanding of heavy tetraquark states.

Findings

Predicted tetraquark masses closely match experimental data

Flux-tube and flip-flop potentials effectively describe tetraquark interactions

Abstract

In this article, we study the ground-state mass of full-heavy tetraquarks $cc\bar c\bar c$ and $bb\bar b \bar b$ with solving the nonrelativistic four-body systems. The flux-tube configurations, the tetraquark four-body potential butterfly, and the dimeson potential flip-flop of SU(3) lattice quantum chromodynamics have been applied to describe the tetraquark interaction. Our numerical analysis indicates that the disconnected and connected static potentials can predict the mass of tetraquark very close to experimental data.
