Ratios of particle yields K$^{*0}$/K and $\phi/$K in panel (a) and K$^{*0}/\pi$ and $\phi/\pi$ in panel (b) as a function of $p_{\mathrm{T}}$ in central Pb--Pb and pp collisions at $\sqrt{s_\mathrm{NN}}$ = 2.76 TeV are shown. Here, (K$^{*0}$+$\overline{\mathrm{K}}^{*0}$), ($\mathrm{K}^{+}$+$\mathrm{K}^{-}$) and ($\pi^{+}$+$\pi^{-}$) are denoted as K$^{*0}$, K, $\pi$, respectively. The statistical and systematic uncertainties are shown as bars and caps respectively.
