Figure Caption

Comparison of the nuclear modification factor of neutral pions extracted in OO collisions to the published one extracted by the CMS collaboration for charged hadrons. To illustrate the expected mass dependence of the RAA, the figure also shows the nuclear modification factor RAA of charged hadrons and charged pions extracted by ALICE in PbPb at 2.76 TeV
