DESCRIPTION:Speakers: Wojciech Florkowski (Institute of nuclear Physics\, 
 Krakow)\nDynamic features of a plasma consisting of gluons whose infrared 
 dynamics is improved by the Gribov-Zwanziger quantization are presented. T
 his approach includes important features of color confinement which set th
 e plasma apart from conventional quasiparticle systems in several aspects 
 [1]. \n\nWe obtain explicit expressions for the transport coefficients $\\
 eta$ and $\\zeta$ (shear and bulk viscosity) and check that they are consi
 stent with the numerical solutions of the kinetic equation.  At high tempe
 rature\, for constant both the Gribov parameter and the relaxation time us
 ed in the kinetic equation\, we find linear scaling of the ratio $\\zeta/\
 \eta$ with the conformal measure  1/3 - $c_s^2$ (sound velocity squared)\,
   which is typical for a strongly coupled system. The newest results obtai
 ned for the temperature dependent Gribov parameter  show also the enhancem
 ent of the bulk viscosity at the phase transition [2].\n\n[1] W. Florkowsk
