Figure Caption

Figure 1 (right): $p_{\mathrm{T}}$ spectra of $\phi$ in pp collisions at $\sqrt{s}$ = 13 TeV for different multiplicity classes, scaled by factors as indicated. The lower panels show the ratios of the multiplicity-dependent $p_{\mathrm{T}}$ spectra to the multiplicity-integrated INEL>0 spectra (with both linear and logarithmic vertical scales). The legend is visible in the left panel (https://alice-figure.web.cern.ch/node/16866.)
