description The high-statistics and high-quality data samples in pp, p–Pb and Pb–Pb collisions at various collision energies collected by the ALICE Collaboration, and the excellent tracking and particle identification capabilities of the Inner Tracking System, the Time-Projection Chamber and the Time-of-Flight detector allow for the detection of rarely produced light (anti-)(hyper-)nuclei. The first (anti-)triton pT spectra in Pb–Pb at the LHC as well as the first (anti-) $^{4}$He p$_{T}$ spectra are presented. Moreover, the p$_{T}$-integrated production yield ratios of deuteron over proton as well as $^{3}$He and triton over proton as a function of charged-particle multiplicity are shown. In addition coalescence parameters $B_{2}$ and $B_{3}$ as a function of pT/$\mathit{A}$ and charge particle multiplicity for several collision systems and energies are discussed. Furthermore, light-nuclei radial and elliptic flow are presented and compared to the flow of lighter particles. These various results are compared with statistical hadronization and coalescence model predictions to provide insight in the production mechanism of light (anti-)nuclei in heavy-ion collisions.
