✦ Synopsis
The screening of colour electric and magnetic fields and plasma oscillations in a high temperature gluon plasma are investigated using linear response theory and self-consistent nonperturbative solutions to the Schwinger-Dyson equation. Static electric fields are screened, with m,', =$ g2Np-(3/a)(% g2N)3"T2.
This result is proven to be gauge invariant in two ways: by computing zoo in temporal axial, Coulomb, and covariant gauges; and by computing the physical free energy of a heavy quark pair in the plasma in temporal axial gauge. To order g3 static magnetic fields are not screened.
