Momentum fluctuations of heavy quarks in the gauge-string duality

arXiv:hep-th/0612143 · doi:10.1016/j.nuclphysb.2007.09.017

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.
