The per-trigger pair-wise yield ratios $R_{i}^{\Lambda/\phi} \equiv Y_{i}^{\text{h--}\Lambda}$/$Y_{i}^{\text{h--}\phi}$ ($i$ = near-side, away-side, UE) as a function of multiplicity in the lower (left) and higher (right) associated momentum ranges. The statistical (systematic) uncertainties are shown as vertical lines (boxes). The ratios predicted by DPMJET are shown as shaded bands, with the width of the band representing the uncertainty of the model. The ratios of the model to the data are also given as shaded bands in the bottom panels, where the width of the band represents the uncertainty of the ratio.
