Molecular and compact four-quark states

Abstract

We study charmonium ($c\bar{c}n\bar{n}$), bottomonium ($b\bar{b}n\bar{n}$) and exotic ($cc\bar{n}\bar{n}$ and $bb\bar{n}\bar{n}$) four-quark states by means of a standard non-relativistic quark potential model. We look for possible bound states. Among them we are able to distinguish between meson-meson molecules and compact four-quark states.
