Fig. 4: Deuteron, triton, and helium-3 production in Pb+Pb collisions at the LHC energies.

Charged-particle multiplicity (dNch/dη) dependence of hadronic re-scattering effects on light nuclei yield ratios Nd/Np (a), \({N}_{{}^{3}{{{{{{{\rm{He}}}}}}}}}\)/Np and \({N}_{{}^{3}{{{{{{{\rm{H}}}}}}}}}\)/Np (b). Theoretical results with and without hadronic dynamics are from Hydro + RKE (shaded bands) and SHM8,16 (lines), respectively. Experimental data points with combined statistical and systematic uncertainties are from the ALICE Collaboration17,39.
