Abstract

The screening length for static QED electric fields in hot 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 summing the leading infrared-divergent diagrams at three-loop and higher order. A comparison is made to the screening length extracted from singlet and nonsinglet susceptibilities as measured in two-flavor lattice QCD.
