Résumé
The interaction properties of cold dark matter particles candidates are known tolead to the structuring of dark matter on scales much smaller than typicalgalaxies. This translates into a large population of dark matter subhalos insideour Galaxy, which impacts the predictions for direct and indirect searches. Wepresent a model for this subhalo population that accounts for the gravitationaleffects experienced by those structures (tidal stripping and disk shocking)while remaining consistent with dynamical constraints. The subhalos mass densityand annihilation profiles are derived. The impact of subhalos on indirectsearches with cosmic rays antiprotons is evaluated using the latest data fromthe AMS-02 experiment.
