  "abstract": "The $p_\\perp$ dependence of the nuclear modification factor $R_{\\rm AA}$ measured in PbPb collisions at the LHC exhibits a universal shape, which can be very well reproduced in a simple energy loss model based on the BDMPS medium-induced gluon spectrum. The scaling is observed for various hadron species ($h^\\pm$, $D$, $J/\\psi$) in different centrality classes and at both colliding energies, $\\sqrt{s}=2.76$ TeV and $\\sqrt{s}=5.02$ TeV. Results indicate an 10-20% increase of the transport coefficient from $\\sqrt{s}=2.76$ TeV to $\\sqrt{s}=5.02$ TeV, consistent with that of particle multiplicity. Based on this model, a data-driven procedure is suggested, which allows for the determination of the first and second moments of the quenching weight without any prior knowledge of the latter.",
