Figure 11

Energy dependence of the $\phi/\pi^{-}$ (upper panel) and $\phi/$K$^-$ ratio (bottom panel) in nuclear (open circles) [4, 5, 50, 52, 53, 54, 55], e$^+$e$^-$ (diamonds) [2, 41, 42, 46, 60], and pp (triangles) [1, 3, 5, 28, 45, 47, 52, 53, 54, 57] collisions. Other $\pi^{-}$ and K$^-$ yields are from [56, 57, 58, 59]. Red squares represent the ALICE data at 0.9 and 7 TeV. The pion and kaon yields at 7 TeV are from [11]. The $\phi$, $\pi^-$, and K$^-$ yields at 0.9 TeV are from [24, 32]. Some points have been displaced horizontally for better visibility. Ratios are calculated from yields at mid-rapidity or in full phase space, except the data at $\sqrt{s}$ = 4.87 GeV [52].
