Steiner-tree confinement and tetraquarks

TL;DR

This paper generalizes the linear confinement model in quarkonium as a minimal tree, revealing new geometric properties and showing it binds tetraquarks more effectively than previous additive models.

Contribution

It introduces a minimal tree confinement model for tetraquarks, offering a novel geometric approach that improves binding predictions over earlier models.

Findings

Minimal tree confinement has interesting geometrical properties.

The model binds tetraquarks more effectively than additive models.

Enhanced understanding of quark confinement mechanisms.

Abstract

The linear confinement in quarkonium is generalised as a minimal tree, with interesting geometrical properties. This model binds tetraquarks more easily than the additive model used in earlier investigations.
