 | The unfolded normalized \DRaxis distributions are measured across different centrality and \pt intervals. Each panel displays distributions for four centrality intervals within a specific \pt bin, with \pt ranges (indicated in each panel) increasing from left to right. In each panel, the black circles show measurements for 0--10\% centrality interval, the red squares for 10--30\%, and the blue-up and green-down triangles for 30--50\% and 50--80\% centrality intervals, respectively. The vertical solid lines represent the statistical uncertainties, while the rectangles and shaded areas represent the correlated and uncorrelated systematic uncertainties, respectively. |
 | The unfolded \DRaxis distributions (black circles) are compared with simulations from \PYTHIA, \HERWIG, and a two-component, represented as colored bands, for the 50--80\% centrality range across different \pt intervals. The vertical solid lines represent the statistical uncertainties, while the rectangles and shaded areas represent the correlated and uncorrelated systematic uncertainties, respectively. Only statistical uncertainties are shown for the simulated distributions. |

 | The unfolded \DRaxis distributions (black circles) are compared with simulations from \PYTHIA, \HERWIG, and a two-component (represented as colored bands), as well as medium q/g and \JEWEL predictions (represented as hatched lines) for the 0--10\% centrality range across different \pt intervals. The vertical solid lines represent the statistical uncertainties, while the rectangles and shaded areas represent the correlated and uncorrelated systematic uncertainties, respectively. Only statistical uncertainties are shown for the simulated distributions. |
