Extending the restricted quantum chromodynamics in SU(2) and SU(3) gauge theories by including quarks and gluons and also by reactivating the suppressed dynamical gauge degrees of freedom, the study of dyonic condensation, quark confinement and superconductivity (dual superconductivity as well as color superconductivity) has been undertaken in extended RCD. It has been shown that the global structure of the underlying gauge symmetry of this extended theory exhibits more information than the conventional QCD may do. It has also been shown that at sufficiently high baryon densities, when nucleons get converted into quark matter, the extended RCD is expected to be in one kind or other of the many different possible color superconductivity phases at low temperature.
