  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.
