Ratios of \Vdecay-triggered yields to charged-hadron triggered (h--h) ones, ${{Y}^{\kzero-\mathrm{h}}_{\Delta\varphi}}/{{Y}^{\mathrm{h-h}}_{\Delta\varphi}}$ (square points) and ${{Y}^{(\lmb+\almb)-\mathrm{h}}_{\Delta\varphi}}/{{Y}^{\mathrm{h-h}}_{\Delta\varphi}}$ (circle points), for \PbPb (top panels) and \pp (bottom panels) collisions in near side (left) and away side (right).
