%X The first measurement of <sub>Λ</sub><sup>3</sup>H and <sup>3</sup><sub>―Λ</sub>―H differential production with respect to transverse momentum and centrality in Pb−Pb collisions at √{s<sub>NN</sub>}=5.02 TeV is presented. The <sub>Λ</sub><sup>3</sup>H has been reconstructed via its two-charged-body decay channel, i.e., <sub>Λ</sub><sup>3</sup>H → <sup>3</sup>He + π<sup>−</sup>. A Blast-Wave model fit of the p<sub>T</sub>-differential spectra of all nuclear species measured by the ALICE collaboration suggests that the <sub>Λ</sub><sup>3</sup>H kinetic freeze-out surface is consistent with that of other nuclei. The ratio between the integrated yields of <sub>Λ</sub><sup>3</sup>H and <sup>3</sup>He is compared to predictions from the statistical hadronisation model and the coalescence model, with the latter being favoured by the presented measurements.
