The product of the acceptance and the resonance reconstruction efficiency $A\times\varepsilon_{\rm rec}$ as a function of $\pt$ for $\rm K^{*0}$ (a) and $\Phi$ (b) mesons, calculated from simulated Pb-Pb collisions at $\snn$ = 2.76 TeV. For the $\Phi$ meson, only five examples for wide centrality intervals are shown. The acceptance $A$ includes the effect of the resonance pair rapidity cut ($|y|< 0.5$). The values shown here do not include the branching ratios. Only statistical uncertainties are shown.
