Quark matter formation in dense stellar objects
... Recent theoretical investigations have [3] shown that, because of attractive quark-quark interaction in isospin-singlet and colour-3 channel, the quark matter, after the phase transition, should be in colour-superconducting phase. The Cooper pairs of the coloursuperconducting phase will have diquark ...
