It has long been understood that the ground state of a superdense quark system, a Fermi liquid of weakly interacting quarks, is unstable with respect to the formation of diquark condensates. This nonperturbative phenomenon is essentially equivalent to the Cooper in-stability of conventional BCS superconductivity. As the quark pairs have nonzero color charge, this kind of superconductivity breaks the SU(3) color gauge symmetry, thus the phe-nomenon is called color superconductivity. However, not much is known about the behavior of quark systems at moderate densities between the formation of baryons and asymptotic freedom. Strong theoretical and experimental evidence suggests that there …
