Figure 4: $p_{\mathrm{T}}$-integrated yields $\mathrm{d}N/\mathrm{d}y$ of K*$^{0}$ (average of the particle and antiparticle) and $\phi$ as functions of $\langle\mathrm{d}N_{\mathrm{ch}}/\mathrm{d}\eta\rangle_{|\eta|<0.5}$. Results are shown for pp collisions at $\sqrt{s}$ = 13 and 7 TeV [1], as well as for p-Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV [2]. The measurements in pp collisions at $\sqrt{s}$ = 13 TeV are also compared with values from common event generators [3-6]. Bars represent statistical uncertainties, open boxes represent total systematic uncertainties, and shaded boxes show the systematic uncertainties that are uncorrelated between multiplicity classes.
