(Anti-)hypertriton-over-(anti-)helium3 ratio as a function of the charged particle multiplicity. In particular, the ratio is computed for 0-10% and 10-40% (green markers) centrality class in Pb-Pb collisions at 5.02 TeV.

 

Detail description

(Anti-)hypertriton-over-(anti-)helium3 ratio as a function of the charged particle multiplicity. In particular, the ratio is computed for 0-10% and 10-40% (green markers) centrality class in Pb-Pb collisions at 5.02 TeV.

The ratios measured in Pb-Pb collisions at 5.02 TeV are compared with those obtained by ALICE in Pb-Pb collisions at 2.76 TeV and by STAR in Au-Au collisions at 200 GeV. As reported in the legend, the ratios are computed using the average of the measured production yields.

Moreover, the ratios for 0-10% in Pb-Pb collisions at 2.76 TeV and 5.02 TeV are compared with predictions from thermal models (GSI-Heidelber, THERMUS, SHARE) and from the Hagedorn resonance gas model.
