- Abstract
In this contribution we present symmetry arguments that can be applied to study the stability of four-quark systems with two different masses. The role played by different symmetry breaking effects and the non-Abelian algebra of color forces is discussed in detail. In the particular case of hidden-flavor all-heavy four-quark states, , the system becomes unstable for standard color-additive models. Differences and similarities between and configurations are presented. In the latter case, its stability when the mass ratio increases was established almost forty years ago. In the former case, we find a kind of metastability between the lowest threshold, and the highest one, .
