Query: Aspects of high density effective theory in QCD   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 quark matter
when the chemical potential is larger than $250\pm 100~{\rm MeV}$ 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.
