摘要：

We study an effective theory of QCD at high density in detail, including the finite temperature effects and the leading order correction in 1/mu expansion. We investigate the Cooper pair gap equation and find that the color-flavor locking phase is energetically preferred at high density. We also find the color-superconducting phase transition occurs in dense quart; matter when the chemical potential is larger than 250 +/- 100 MeV and the temperature is lower than 0.57 times the Cooper pair gap in the leading order in the hard-dense-loop approximation. The quark-neutrino four-Fermi coupling and the quark-axion coupling receive significant corrections in dense quark matter. (C) 2000 Elsevier Science B.V. All rights reserved.
