Query: Three-Flavor QCD at High Density: Color Flavor Locking and Chiral
  Symmetry Breaking   We propose a symmetry breaking scheme for QCD with three massless quarks at
high baryon density wherein the color and flavor
SU(3)_{color}xSU(3)_{L}xSU(3)_{R} symmetries are broken down to the diagonal
subgroup SU(3)_{color+L+R} by the formation of a condensate of quark Cooper
pairs. We discuss general properties that follow from this hypothesis,
including the existence of gaps for quark and gluon excitations, the existence
of Nambu-Goldstone bosons which are excitations of the diquark condensate, and
the existence of a modified electromagnetic gauge interaction which is unbroken
and which assigns integral charge to the elementary excitations. We present
mean-field results for a Hamiltonian in which the interaction between quarks is
modelled by that induced by single-gluon exchange. We find gaps of order 10-100
MeV for plausible values of the coupling. We discuss the effects of nonzero
temperature, nonzero quark masses and instanton-induced interactions on our
results.
