Left: inelastic interaction cross section for antitritons with the two analysis methods on an average material element of the ALICE detector as a function of the momentum $p$ at which the interaction occurs. Dashed black lines represent the default GEANT4 parameterisations for antitritons. Right: comparison between the results reported in the left panel and the results for $^3\overline{\rm He}$ inelastic cross section measured in Pb$-$Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV from Ref. [38]. Note that $^3\overline{\rm He}$ nuclei can be clearly identified in both TPC and TOF detectors over a much wider momentum range than $^3\overline{\rm H}$. In both panels, boxes show the statistical and systematic uncertainties summed in quadrature.
