Production yields of the hypertriton (red) and anti-hypertriton (blue) via 2 body decay channel (B.R. = 25%) as a function of the charged particle multiplicity. The production yields are obtained by analysing the 2015 data sample of Pb-Pb collisions at 5.02 TeV and in three centrality classes (0-10%, 10-30%, 30-50%).
Production yields of the hypertriton (red) and anti-hypertriton (blue) via 2 body decay channel (B.R. = 25%) as a function of the charged particle multiplicity. The production yields are obtained by analysing the 2015 data sample of Pb-Pb collisions at 5.02 TeV, which consists in 104.9 x 10^{6} selected events, and in three centrality classes (0-10%, 10-30%, 30-50%).
