Description
Jet modification by the hot and dense medium created in heavy-ion collisions has been demonstrated by a variety of observables.
A modification like the softening and broadening of the jet fragmentation can be probed optimally with 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 can thus provide less-biased insight into how the medium affects the away side jet fragmentation.
The aim of the presented analysis is to show the modification of the fragmentation function f($z_{\mathrm{T}}$) due to the medium and pin down
the energy lost and recovered at different angles away from the jet axis.

This poster outlines the analysis strategy and performance for $\gamma$-hadron correlations with the recently collected Pb--Pb data
at \ensuremath{\sqrt{s_\mathrm{NN}}}=5.02\,TeV, measured with the EMCal and DCal detectors of the ALICE experiment.
