We compute the potential between a qq-bar color-singlet state for N=4 SUSY with gauge group SU(N) at finite temperature T, large distances rT>>1, and weak coupling g. As a first step, we only consider the electric modes and compute the Debye mass m{sub D}, where we find that each of the 8(N{sup 2}-1) bosonic degrees of freedom contributes to m{sub D}{sup 2} (on average) with (N/N{sup 2}-1)(1/6)g{sup 2}T{sup 2}, while each of the 8(N{sup 2}-1) fermionic degrees of freedom contributes (on average) with (N/N{sup 2}-1)(1/12)g{sup 2}T{sup 2}, yielding m{sub D}{sup 2}=2Ng{sup 2}T{sup 2}. Then, motivated by results obtained in the literature from both the weak-coupling results in QCD and the large-coupling investigations of N=4 SUSY through AdS/CFT, we attempt to include magnetic mode corrections. Our results illustrate that, for this particular computation, N=4 SUSY is in striking qualitative agreement with QCD.
