Abstract

Using the gauge-string duality, I compute two-point functions of the force acting on an external quark moving through a finite temperature bath of N = 4 super-Yang-Mills theory. I comment on the possible relevance of the string theory calculations to heavy quarks propagating through a quark-gluon plasma.
