Abstract.
The vacuum state of SU(3) gluodynamics at high temperature is investigated. A consistent approach including the calculation of the spontaneously generated constant chromomagnetic isotopic H 3 and hypercharge H 8 fields and the polarization operator of charged gluons in this background is applied. It is shown within the effective potential, taking into consideration the one-loop plus daisy diagrams, that the specific values of the fields yield a global minimum to the free energy. The spectrum of the transversal charged modes is stable at high temperature due to the calculated gluon magnetic mass which accounts for the fields. This leads to stable chromomagnetic fields in the deconfinement phase of QCD. A comparison with results of other approaches is made.
