Query: Phase Structure of Hot and/or Dense QCD with the Schwinger-Dyson
  Equation   We investigate the phase structure of hot and/or dense QCD using the
Schwinger-Dyson equation (SDE) with the improved ladder approximation in the
Landau gauge. We show that the phase transition from the two-flavor color
superconducting (2SC) phase to the quark-gluon plasma (QGP) phase is of second
order, and that the scaling properties of the Majorana mass gap and the diquark
condensate are consistent with mean field scaling. We examine the effect of the
antiquark contribution and find that setting the antiquark Majorana mass equal
to the quark one is a good approximation in the medium density region. We also
study the effect of the Debye screening mass of the gluon and find that
ignoring it causes the critical lines to move to the region of higher
temperature and higher chemical potential.
