DESCRIPTION:Speakers: CZAJKA\, Alina (Jan Kochanowski University)\nThe N=4
  super Yang-Mills plasma is studied in the regime of weak coupling. Collec
 tive excitations and collisional processes are discussed. Since the Keldys
 h-Schwinger approach is used\, the collective excitations in both equilibr
 ium and non-equilibrium plasma are under consideration. The dispersion equ
 ations of gluon\, fermion\, and scalar modes are written down and the self
 -energies\, which enter the equations\, are computed in the Hard Loop Appr
 oximation. The self-energies are discussed in the context of effective act
 ion which is also given. The gluon modes and fermion ones appear to be the
  same as those in the QCD plasma of gluons and massless quarks. The scalar
  modes are as of free relativistic massive particle. The binary collisiona
 l processes\, which occur at the lowest nontrivial order of the coupling c
 onstant\, are reviewed and then the transport properties of the plasma are
  discussed. The N=4 super Yang-Mills plasma is finally concluded to be ver
 y similar the QCD plasma of gluons and light quarks. The differences mostl
 y reflect different numbers of degrees of freedom in the two systems.\n\nh
