摘要：

We use perturbation theory to compute the diffusion coefficient of a heavy quark or scalar moving in N = 4 SU(N-c) Super Yang-Mills plasma to leading order in the coupling and the ratio T/M << 1. The result is compared both to recent strong coupling calculations in the same theory and to the corresponding weak coupling result in QCD. Finally, we present a compact and simple formulation of the Lagrangian of our theory, N = 4 SYM coupled to a massive fundamental N = 2 hypermultiplet, which is well-suited for weak coupling expansions.
