Invariant yields for (a) K$^{*0}$ and (b) $\phi$ mesons normalized to the number of inelastic pp collisions at $\sqrt{s}$ = 2.76 TeV. Invariant yield is calculated by taking the value of $p_{\mathrm{T}}$ at the corresponding bin center. The statistical uncertainties on the data are shown by bars and the systematic uncertainties by boxes. The results are compared with model calculations from PYTHIA 8.14 [33], PHOJET [34,35], PYTHIA D6T [37], PYTHIA ATLAS-CSC [38] and PYTHIA PERUGIA [38] as shown by different dashed lines. The lower panel for both K$^{*0}$ and $\phi$ shows the model to data ratio.
