The study of the heavy quark–antiquark system is an old topic (see [1] for earlier references). Here we will concentrate on recent developments based on effective field theories. For large enough masses, these systems can be considered to be non-relativistic (NR) and are then characterized by, at least, three widely separated scales: hard (the mass m, of… CONTINUE READING
