Query: Relaxation Near the Critical Point   I present an analysis of the relaxation rate for long-wavelength fluctuations
of the order parameter in an O(N) scalar theory near the critical point. Our
motivation is to model the non-equilibrium dynamics of critical fluctuations
near the chiral phase transition in QCD. In the next-to-leading order in the
large $N$ expansion we find a critical slowing down regime, i.e. an increasing
of the relaxation time of long wavelengths fluctuations. This result suggests,
for near critical systems, relevant deviations from thermal equilibrium for the
distribution functions of low-energy particles and could have important
phenomenological consequences in Heavy Ions Collision and in the Early Universe
Cosmology.
