Abstract

We compute the momentum broadening of an energetic parton as it moves through strongly interacting matter, using the gravity dual of a non conformal gauge theory with matter in the fundamental representation. Our approach defines a family of theories, all of which have logarithmic running of the couplings in the far IR but becomes almost conformal in the far UV. For a given set of degrees of freedom, we obtain average transverse momentum square of the parton as a function of temperature and compare with results obtained from the AdS/CFT correspondence.
