Macroscopic QCD and quark–gluon plasma

We propose the equations of macroscopic QCD and consider the high-energy behavior of the quark–gluon medium described by these equations. The parton currents traversing it induce the emission of Cherenkov gluons, the wake effect, and the transition radiation. Comparison with experimental data reveals a quite large value of the chromopermittivity of the medium. The dispersion equations show that the proper modes of the medium develop instability.
