The first measurement of $_\Lambda^3H$ and $_{\bar\Lambda}^3\bar{H}$ differential production with respect to transverse momentum and centrality in Pb–Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV is presented. The $_\Lambda^3H$ has been reconstructed via its two-charged-body decay channel, i.e., $_\Lambda^3H$→$^3He+\pi^−$. A Blast-Wave model fit …
