Abstract:
We review the multi-component decaying dark matter (DM) scenario to explain the possible cosmic ray excesses in the positron fraction, the positron and electron respective fluxes, and the total [Formula: see text] flux observed by AMS-02. We show that the two-component DM model can fit the AMS-02 datasets. In particular, we demonstrate that the heavier DM component with its mass around 1 TeV dominantly decaying through the [Formula: see text] and [Formula: see text]-channels describes the high-energy behavior of the total [Formula: see text] flux data above 500 GeV, while the lighter one of O(100) GeV mainly through the [Formula: see text]-channel explains the substructure around 100 GeV.
