| Abstract: The angular correlation between two different jet axes for a given jet of R= 0.4, obtained by using two different clustering algorithms on the same collection of anti-kT jets, is studied using lead-lead collision data at a center-of-mass energy per nucleon pair of 5.02 TeV. The dataset, corresponding to an integrated luminosity of 0.662 nb−1, was collected with the CMS detector at the CERN LHC. The jet axis correlations are examined across collision centrality selections and jet pT intervals. A centrality-dependent evolution of the measured distributions is observed, with a progressive narrowing seen in more central events. This narrowing could result from medium-induced modification of the internal jet structure or reflect color-charge effects in energy loss. The new measurements study jet substructure in previously unexplored kinematic domains and show great promise for providing new insights on the color charge dependence of energy loss to jet quenching models. | ||
