Description
I will discuss the implication for dark matter (DM) indirect searches of the recent precise measurements of cosmic-ray (CR) antiprotons from AMS-02 .
With respect to previous works we use a new updated CR propagation model
consistent with the AMS-02 data.
Furthermore, we fit at the same time, in a self-consistent way,
both DM and the propagation parameters.
We find a significant indication of a DM signal for DM masses near 80 GeV,
which, interestingly, is also compatible with the similar excess present in the Galactic center in gamma rays. Possible systematic effects will be also discussed.
In terms of DM exclusion limits, we find stringent constraints a factor of 4-5
stronger than limits from gamma-ray observations of dwarf galaxies.
