Measurement of 3ΛH production in Pb-Pb collisions at root sNN=5.02 TeV

Popis výsledku v původním jazyce

The first measurement of H-3(Lambda) and 3/Lambda(H) over bar differential production with respect to transverse momentum and centrality in Pb-Pb collisions at root(NN)-N-S = 5.02 TeV is presented. The H-3(Lambda) has been reconstructed via its two-charged-body decay channel, i.e., H-3(Lambda) -> He-3 + pi(-). A Blast-Wave model fit of the..T-differential spectra of all nuclear species measured by the ALICE collaboration suggests that the H-3(Lambda) kinetic freeze-out surface is consistent with that of other nuclei. The ratio between the integrated yields of H-3(Lambda) and He-3(Lambda) is compared to predictions from the statistical hadronisation model and the coalescence model, with the latter being favoured by the presented measurements.
