Light (anti-)nuclei production and elliptic flow at the LHC with ALICE

Results on the production of stable light nuclei, including deuterons, $^3$He, $^4$He and the corresponding anti-nuclei, in Pb–Pb collisions at $\sqrt{s_{NN}}$=2.76TeV and $\sqrt{s_{NN}}$=5.02TeV are presented and compared with theoretical predictions and with the results in small systems to provide insight into the production mechanisms of (anti-)nuclei at colliders.The experimental results are presented giving a critical view of their comparison to the expectations from coales-cence and hydrodynamic models that aim at describing both the $p_T$-spectra and the elliptic flow.
