 | The PbPb to \pp ratio as a function of $\Delta r$ for leading jet shapes, $\rhoPbPb / \rhoPp$, in different centrality bins for $0 < \xj < 0.6$ (upper row), $0.6 < \xj < 0.8$ (middle row) and $0.8 < \xj < 1.0$ (lower row) dijet selections. The leading jet shape ratio for all dijets, \ie, without any selection on the dijet momentum balance are also shown in each row for comparison. The error bars represent the statistical uncertainties and the shaded areas the systematic uncertainties. |
