Invariant-mass distribution of selected ${}_{\Lambda}^{3}\mathrm{H}$ candidates in the centrality class 0$-$10% and $p_{\rm T}$ interval 3 $<$ $p_{\rm T}$ $<$ 3.5 $\mathrm{Ge\kern-.1emV/}c$ fitted with a function which is the sum of a double-sided Crystal Ball signal and an exponential background. Vertical lines represent the statistical uncertainties.
