Quark Pauli blocking in hadronic matter

We show that the Phi-derivable formulation of the cluster virial expansion for quark matter contains the quark Pauli blocking effect in the lowest order expansion with respect to the backreaction of hadrons on the quark dynamics. We discuss this effect for the pion gas and for nuclear matter within a nonrelativistic potential model and estimate its enhancement by partial chiral symmetry restoration in dense matter.
