Ratios of the average production yield of $m$ multi-strange baryons $\rm \langle Y_{m baryon} \rangle$, to those of $n$ single-strange particles, $\rm \langle Y_{n {\rm K}^{0}_{\rm{S}}} \rangle$ (left) and $\rm \langle Y_{n \Lambda} \rangle$ (right), as a function of the unbiased average charged-particle multiplicity, ${\langle\mathrm{d}N_\mathrm{ch}/\mathrm{d}\eta\rangle}_{\left | \eta \right |< 0.5}$(V0M class). The measurements are compared to MC predictions from PYTHIA 8 Monash 2013 (dotted lines), PYTHIA 8 QCD-CR + Ropes (continuous lines) and EPOS LHC (dashed lines).
