We explore phenomenological signatures of light quark jet quenching within the AdS/CFT correspondence. Firstly, we note that the numerical studies indicate a linear path dependence of the instantaneous energy loss of light quarks modeled as falling strings. Secondly, we propose a phenomenological model for generic description of their energy loss and use it to compute the nuclear modification factor RAA for light quarks in an expanding plasma with Glauber initial conditions. Comparing with the light hadron RAA data at the LHC, a qualitative agreement is shown. Thirdly, we show how the observed quantitative disagreement can be partially alleviated by including the effects from higher derivative corrections to AdS5.
