Energy dependence of the K$^*$/K$^-$ (upper panel) and $\phi$/K$^{*}$ (lower panel) ratio in e$^+$e$^-$ (diamonds), and pp (triangles) collisions. Red squares represent the data from the ALICE experiment for 7 TeV pp collisions, K$^-$ yields are from. Open circles represent the same ratios in central nucleus-nucleus collisions from. Some points have been displaced horizontally for better visibility. Ratios are calculated from yields at mid-rapidity or in full phase space.
