Figure 6

Comparison of transverse momentum spectra of \kstar (left panel) and \phim (right panel) in central (0-10\%) and mid-central (40-50\%) centrality classes in \PbPb collisions at \snn $=$ 5.02 (solid marker) and 2.76 (open marker) \TeV~. The lower panels show the ratio of the \pt spectra at \snn~$=$~5.02~\TeV to those from \snn~$=$~2.76~\TeV. The statistical uncertainties on the data are shown by bars and the systematic uncertainties by boxes.
