Abstract
The screening length for static quantum-electrodynamic electric fields in hot quantum chromodynamics (QCD) is computed using hadronic degrees of freedom at low temperature and quark-gluon degrees of freedom at high temperature. The high temperature result is equivalent to computing the photon self-energy to two-loop order in QCD plus summation of the leading infrared divergent diagrams at three-loop and higher order. Comparison is made with the screening length extracted from singlet and nonsinglet susceptibilities as measured in two-flavor lattice QCD.
