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.
