Query: Phase diagram of QCD with two degenerate staggered quarks   We present preliminary results about the critical line of QCD with two
degenerate staggered quarks at nonzero temperature and chemical potential,
obtained by the method of analytic continuation. As in our previous studies
with different numbers of colors and flavors, we find deviations from a simple
quadratic dependence on the chemical potential. We comment on the shape of the
critical line at real chemical potential and give an estimate of the curvature
of the critical line, both for quark chemical potential and isospin chemical
potential.
