Abstract
We use our non-conformal holographic bottom-up model for QCD described in Ficnar et al (2011 Nucl. Phys. A 855 372) to further study the effect of the QCD trace anomaly on the energy loss of both light and heavy quarks in a strongly coupled plasma. We compute the nuclear modification factor RAA for bottom and charm quarks in an expanding plasma with Glauber initial conditions. We find that the maximum stopping distance of light quarks in a non-conformal plasma scales with the energy with a temperature- (and energy)-dependent effective power.
