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

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.
