A White Paper on keV sterile neutrino Dark Matter (2016, methodology): “Lastly, limits from positrons were derived in [368] from the AMS-02 measurements of the positron fraction [369] and the positron flux [370].”
A tale of tails: Dark matter interpretations of the Fermi GeV excess in light of background model systematics (2014, background): “The most relevant indirect constraints on DM models come from the nonobservation of spectral features in the AMS-02 measurements of CR positrons [82,83], and PAMELA observations of the CR antiprotons [84–89] (see however Ref.”
Background model systematics for the Fermi GeV excess (2014, background): “For leptonic two-body final states the strongest limits come from a spectral analysis of the positron fraction measured by AMS-02 [132, 133], which excludes a thermal rate for χχ→ e+e− (χχ→ µ+µ−) up to DM masses of mDM ' 200 GeV (100 GeV), so that this channel can only play a very subdominant role i”
