  "description": "<p>The first measurement of ${}_{\\Lambda }{}^{3}H$ and ${}_{\\stackrel{\u203e}{\\Lambda }}{}^{3}\\stackrel{\u203e}{H}$ differential production with respect to transverse momentum and centrality in Pb\u2013Pb collisions at $\\sqrt{{s}_{\\mathrm{NN}}}\\phantom{\\rule{0.25em}{0ex}}=\\phantom{\\rule{0.25em}{0ex}}5.02$ TeV is presented. The ${}_{\\Lambda }{}^{3}H$ has been reconstructed via its two-charged-body decay channel, i.e., ${}_{\\Lambda }{}^{3}H\\to {}^{3}\\mathrm{He}+{\\pi }^{-}$. A Blast-Wave model fit of the ${p}_{T}$-differential spectra of all nuclear species measured by the ALICE collaboration suggests that the ${}_{\\Lambda }{}^{3}H$ kinetic freeze-out surface is consistent with that of other nuclei. The ratio between the integrated yields of ${}_{\\Lambda }{}^{3}H$ and ${}^{3}\\mathrm{He}$ is compared to predictions from the statistical hadronisation model and the coalescence model, with the latter being favoured by the presented measurements.</p>",
