Description
The medium modification of jets continues to be studied in greater and greater detail, ranging from their absolute yields to substructure measurements. A key problem has always been to accurately determine the jet energy calibration in order to establish the influence of the hot QCD medium on the observed jet properties. A way to circumvent this ambiguity is the measurement of direct $\gamma$-hadron correlations. The direct photon, produced in hard scatterings back-to-back with a parton, serves as a calibration of the away-side jet and thus provides less-biased insight into how the medium affects the away-side jet fragmentation. We ultimately aim to measure the modified fragmentation function f($z_{\mathrm{T}}$) and its dependencies on several quantities like the $\gamma$-trigger $p_{T}$ or associated hadron $p_{T}$ to understand the $z_{T}$ dependence.

This poster will demonstrate our capability to measure inclusive $\gamma$-hadron and $\pi^{0}$-hadron correlation functions. Results will be presented for Pb--Pb data at \ensuremath{\sqrt{s_\mathrm{NN}}}=5.02\,TeV, measured with the EMCal and DCal detectors of the ALICE experiment.
