Introduction to the Quark State

The four-quark state is an imaginary meson formed by four quarks. In principle, modern strong interaction theory quantum chromodynamics allows the existence of four quark states. However, there has been no confirmed report so far to discover the four-quark state. Any discovery of the four-quark state can prove the existence of singular hadrons, which is not allowed by the definition of the quark model.
