Invariant yields of (a) K$^{*0}$ and (b) $\phi$ mesons in various centrality classes in Pb-Pb collisions at $\sqrt{s_\mathrm{NN}}$ = 2.76 TeV Invariant yield is calculated by taking the value of $p_{\mathrm{T}}$ at the corresponding bin center. The statistical and systematic uncertainties are shown as bars and boxes, respectively. The normalization uncertainty is not shown here, but is given in Tab. 3. | |
