Most people nowadays think of hadrons as made of quark constituents trapped in a potential well. The well may or may not be infinitely high; it must rise at least above the present energy range to make free quarks so rare. As in any potential well, we expect to find excited states right up to the top of the well. We also expect the density of levels to rise rapidly with mass since there are so many ways to form a highly excited level: any one of the valence quarks can be raised to an excited level, or more than one can be raised at the same time, or quark pairs or gluons can be added.
