Abstract
Assuming that the positron excess and the unconfirmed anti-proton excess in AMS-02 data are both consequences of dark matter annihilations, here we introduce the multi-channel approach in dark matter searching to perform a general analysis on exploring possibilities to describe the data from an almost model-independent perspective. We then conclude that the data show a preference for DM species with τ − τ + dominant channel and Mχ∼1 TeV and suggest a dark matter density distribution with a rather large inner slope.
