AbstractCosmic-ray (CR) anti-nuclei are often considered important observables for indirect dark matter (DM) detection at low kinetic energies, below GeV per nucleon. Since the primary CR fluxes drop quickly towards high energies, the secondary anti-nuclei in CR are expected to be significantly suppressed in high energy regions (greater than or similar to 100 GeV per nucleon). If DM particles are heavy, the annihilation productions of DM can be highly boosted, and thus the fluxes of anti-nuclei produced by DM annihilation may exceed the secondary background at high energies, which opens a high energy window for indirect DM detection. We investigate the possibility of detecting heavy DM particles which annihilate into high energy anti-nuclei. We use the Monte Carlo generators PYTHIA, EPOS-LHC and DPMJET and the coalescence model to simulate the production of anti-nuclei, and constrain the DM annihilation cross-sections by using the AMS-02 and HAWC antiproton data and the HESS galactic center gamma-ray data. We fmd that the conclusion depends on the choice of DM density profiles. For the "Cored" type profile with a DM particle mass greater than or similar to 10 TeV, the contributions from DM annihilation can exceed the secondary background in high energy regions, which opens the high energy window, while for the "Cuspy" type profile, the excess disappears.
