Figure Caption

Isolated photon-tagged fragmentation function for pp (red) and p–Pb data (blue) at sqrt(s) = 5.02 TeV as measured by the ALICE detector. The boxes represent the systematic uncertainties while the vertical bars indicate the statistical uncertainties. The dashed green line corresponds to PYTHIA 8.2. The chi2 test for the comparison of pp and p–Pb data incorporates correlations among different zT intervals. A constant that was fit to the ratio including
statistical and systematic uncertainties is shown as grey band, with the width indicating the uncertainty on the fit.
