Isolated photon–hadron correlation functions for pp (red) and p–Pb (blue) data at sqrt(s) = 5.02 TeV as measured by the ALICE detector. The different panels represent three different zT bins. The correlation functions are projected over the range |delta phi|<1.2. The darker bands at zero represents the uncertainty from the underlying event estimation in pp and p–Pb. The underlying event was estimated over the range 0:4 < |delta phi|< 1.6. The vertical bars represent statistical uncertainties only. The boxes indicate the systematic uncertainties. The dashed green line represents the isolated photon–hadron correlation function obtained with PYTHIA 8.2 Monash Tune. “p” is the p-value for the hypothesis that the pp and p–Pb data follow the same true correlation function.
