✦ Synopsis

We study the thermal properties of QCD in the presence of a small quark chemical potential ,L Derivatives of the phase transition point with respect to p are computed at /.L = 0 for 2 and 3 flavors of p-4 improved staggered fermions on a 163 x 4 lattice. Moreover we contrast the case of isoscalar and isovector chemical potentials, quantify the effect of p # 0 on the equation of state, and comment on the screening effect by dynamical quarks and the complex phase of the fermion determinant in QCD with p # 0.

The talk is an introduction into diquark condensation phenomena which occur in QCD at high energy density. They are driven by instantons and instanton-antiinstanton pairs (or "molecules"), which generate attraction in some qq channels. A number of phases is possible, with or without restoration of

The phase diagram of strongly interacting matter is explored as a function of temperature and baryon number density. We investigate the possible simultaneous formation of condensates in the conventional quark-anti-quark channel (breaking chiral symmetry) and in a quark-quark channel leading to color
