Abstract
The nonabelian screening potential is calculated in the temporal axial gauge. The Slavnov-Taylor identity is used to construct the three-glu on vertex function from the inverse gluon propagator. After solving th e Schwinger-Dyson equation beyond leading order we find that the obtai ned momentum dependence of the gluon self-energy at high temperature d oes not correspond to an attractive QCD-Debye potential, but instead i t is repulsive and power behaved (congruent-to 1/r6) at large distance .
