Abstract:
A survey devoted to A0A_0-condensate in gauge theories at high temperature is presented. Both the theoretical foundations of the spontaneously generated condensate and known methods of its calculation are discussed. As most important consequence the SU(N)SU(N) global symmetry breakdown is investigated in details. Influence of A0A_0 on matter fields is studied in different aspects. Some new results concerning this subject are reported as well.
  • gauge field theory: SU(N)
  • gauge boson: condensation
  • temperature: high
  • lattice field theory: action
  • Wilson loop
  • confinement
  • critical phenomena
  • path integral
  • effective action
  • perturbation theory: higher-order
