The wave function is the product of four parts describing the spatial, spin, flavor, and color configuration. The Pauli principle requires the baryon to be antisymmetric with respect to the exchange of any pair of quarks.

One of the few theorists to foresee why two charm quarks might mingle was Jean-Marc Richard, now at the Institute of Physics of the 2 Infinities in Lyon, France. In 1982, he and two colleagues studied a simple quark model and initially found that four quarks would rather form two pairs — mesons.
