Macroscopic QCD and quark-gluon plasma

摘要

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.
