Figure Caption

Strangeness population factor S_{3} = (Hypertriton/Helium-3) x (proton/lambda) measured in Pb-Pb collisions at 5.02 TeV in 0-10% centrality class (blue marker) compared with the published results (ALICE, STAR, E864, HypHI) and with theoretical predictions.

Detail description

Strangeness population factor S_{3} = (Hypertriton/Helium-3) x (proton/lambda) measured in Pb-Pb collisions at 5.02 TeV in 0-10% centrality class (blue marker).

S_{3} is plotted as a function of the centre-of-mass energy and is compared with the published results from ALICE (red marker, 0-10% Pb-Pb at 2.76 TeV), STAR (light blue marker, 0-80% Au-Au at 200 GeV), E864 (green marker, 0-10% Au-Pt at 5 GeV) and HypHI (orange marker, ^{16}Li-^{12}C).

The results is also compared with theoretical predictions. In particular predictions from coalescence approach, which were done up to top RHIC energies, and from Hybrid UrQMD and GSI-Heidelberg, done also for the LHC energies.
