Measurement of $π^0$-hadron correlations relative to the event plane in semicentral Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV

Per-trigger yields of $\pi^{0}-$hadron correlations were measured in semicentral Pb--Pb collisions at $\sqrt{s_{\rm NN}}=5.02~$TeV in ALICE at the LHC. The reconstructed $\pi^{0} \rightarrow \gamma \gamma$, with a transverse momentum of $11 3$GeV$/c$, no significant event-plane dependence is observed within uncertainties. The results are compared with predictions from the JEWEL model, which implements jet energy loss in an expanding medium. JEWEL predicts no significant modification of either the near- or away-side associated yields, independent of whether medium recoils are included. The observed behavior may indicate the presence of additional energy-loss mechanisms beyond those governed by path-length dependence.
