Prospects of detecting dark matter through cosmic-ray antihelium with the antiproton constraints

Cosmic-ray (CR) antihelium can be an important observable for dark matter (DM) indirect searches due to extremely low secondary backgrounds towards low energies. In most DM models, the predicted CR antihelium flux is strongly correlated with that of CR antiprotons. Thus the upper limits on the DM annihilation cross sections from the current antiproton data can be used to place stringent limits on the maximal antihelium flux for the same model. Making use of the latest AMS-02 data on the antipro...
