Non-Abelian dynamics and heavy multiquarks, Steiner-tree confinement in hadron spectroscopy

TL;DR

This paper reviews multiquark state predictions and introduces a Steiner-tree confinement model that suggests the potential stability of certain heavy multiquarks with exotic quantum numbers.

Contribution

It presents a novel model combining flip-flop and Steiner trees to predict stable multiquark states, especially involving heavy quarks.

Findings

Stable multiquarks predicted with Steiner-tree confinement

Configurations with multiple heavy quarks are potentially stable

Exotic quantum number states are feasible in this model

Abstract

A brief review is first presented of attempts to predict stable multiquark states within current models of hadron spectroscopy. Then a model combining flip-flop and connected Steiner trees is introduced and shown to lead to stable multiquarks, in particular for some configurations involving several heavy quarks and bearing exotic quantum numbers.
