So far, no direct observations of anti-nuclei heavier than antiprotons have been reported but many predictions claim a large signal-to-background ratio for WIMPs annihilations into final states containing antideuterons or antihelium nuclei. This project attacks in a systematic way the modelling of light anti-nuclei formation and its propagation within the interstellar medium. The project is based on the interpretation of the precision measurements of antideuteron and antihelium nuclei produced at the ALICE experiment at the LHC. We will finally estimate the anti-nuclei yields for AMS02 and GAPS stemming from cosmic ray interaction or dark matter annihilation/decay.
