Comparison of the nuclear modification factor in \xexe and \pbpb collisions integrated over identical regions in \pt as a function of \avg{\dnchdeta}. The vertical brackets indicate the quadratic sum of the total systematic uncertainty in the measurement and the overall normalization uncertainty in \avTAA.The horizontal bars reflect the RMS of the distribution in each bin. The dashed lines show results from power-law fits to the data and are drawn to guide the eye.
