摘      要：The color superconductivity of Quantum Chromodynamics(QCD)matter at high baryon density,such as in the core of the neutron star,has been extensively studied,see Ref.[1]for a review and references *** studies have shown that consequences of the large superconducting gap will be observed in astrophysics or in laboratory heavy-ion ***,this has not been robustly confirmed by a first principle calculation due to the sign problem of lattice Monte Carlo simulations in dense QCD *** has therefore been proposed that one may understand quark matter at finite baryon density in other,simpler QCD-like *** example,in Nc=2 gauge may theory,the fermion determinant is guaranteed to be real at nonzero chemical potential thanks to an additional anti-unitary symmetry,allowing a discrete evaluation for both fundamental and adjoint ***,the flavor space is extended from the usual SU(Nf)to the larger SU(2N1f).
