Studies on the static screening effect in a pure gluon plasma by an extensive numerical simulation of lattice QCD is reported here. The simulation is done on a 24×24×24×Nₜ lattice with Nₜ=4,6,16 at various temperatures above the phase transition. Our results show that the hot gluon plasma fits a Debye-screening picture very well and the potential for each representation of a qq̄ pair system is of Yukawa-type potential. Also, accidentally, we find that the potential tends to agree with the naive "lowest-order perturbative prediction" when T becomes much larger than Tc.
