Ratio of $\Ls$ to $\Lam$ in inelastic pp collisions at $\s$ $\mathrm{=}$ 7 TeV, p--Pb collisions at \mbox{$\sn$ $\mathrm{=}$ 5.02 TeV}  and in NSD pp collisions at $\s$ $\mathrm{=}$ 200 GeV . Statistical uncertainties (bars) are shown together with total (hollow boxes) and multiplicity-uncorrelated (shaded boxes) systematic uncertainties. The results are compared with several model calculations (see text for details).
