Viscosity of high energy nuclear fluids

Relativistic high energy heavy ion collision cross sections have been interpreted in terms of almost ideal liquid droplets of nuclear matter. The experimental low viscosityof these nuclear fluids have been of considerable recent quantum chromodynamicinterest. The viscosityis discussed here in terms of the string fragmentation models wherein the temperature dependence of the nuclear fluid viscosityobeys the Vogel–Fulcher–Tammann law.
