Query: Soft Modes at the Critical End Point in the Chiral Effective Models   At the critical end point in QCD phase diagram, the scalar, vector and
entropy susceptibilities are known to diverge. The dynamic origin of this
divergence is identified within the chiral effective models as softening of a
hydrodynamic mode of the particle-hole--type motion, which is a consequence of
the conservation law of the baryon number and the energy.
