Abstract: (APS)
A systematic perturbation theory for high-density quark gas is developed. The ground-state thermodynamic potential is evaluated up to the second order in the Gell-Mann-Low coupling αs(M). Phenomenological analysis of the resulting equation of state suggests that the neutron-quark matter phase transition occurs at neutron matter densities nB<2 baryon/fm3 provided 0.2<αs(3 GeV)<0.3. The result supports the conjecture that superheavy stellar objects may exist in the quark rather than in the neutron phase. The production of quark matter in heavy-ion collisions is also discussed briefly.
