The rst measurement of &sup(3)&sub(*L)H and &sup(3)&sub(*L)H^- differential production with respect to transverse momentum and centrality in Pb–Pb collisions at *%𝑠&sub(NN) = 5.02 TeV is presented. The &sup(3)&sub(*L)H has been reconstructed via its two-charged-body decay channel, i.e., &sup(3)&sub(*L)H *> &sup(3)He + *p&sup(−). A Blast-Wave model t of the 𝑝&sub(T)-dierential spectra of all nuclear species measured by the ALICE collaboration suggests that the &sup(3)&sub(*L)H kinetic freeze-out surface is consistent with that of other nuclei. The ratio between the integrated yields of &sup(3)&sub(*L)H and &sup(3)He is compared to predictions from the statistical hadronisation model and the coalescence model, with the latter being favoured by the presented measurements.
