In particle physics, a glueball is a hypothetical composite particle. It consists solely of gluon particles, without valence quarks. Such a state is possible because gluons carry color charge and experience the strong interaction. Glueballs are extremely difficult to identify in particle accelerators, because they mix with ordinary meson states. T...

A neutral meson that consists of a ball of gluons (sometimes referred to as gluonium). Because gluons have color, like quarks they feel the strong force (even though they are the carriers of the force) and are confined by it s that a free colored gluon can never be seen.
