Description
Weakly Interacting Massive Particles (WIMPs) have been the target of
cosmic ray experiments for decades. AMS-02 is the first experiment which can
realistically probe WIMP annihilation signals in the antiproton channel. Due to
the tiny experimental errors, uncertainties in the astrophysical background
have become the most limiting factor for the dark matter detection. I will use
the combination of antiproton, boron to carbon and positron data in order to
systematically reduce uncertainties related to the propagation of charged
cosmic rays. In addition, I will use a wide collection of accelerator data to
improve the calculation of the astrophysical antiproton source term. Finally, I
will present a spectral search for dark annihilation in the AMS-02 antiproton
data. I will also comment on prospects of dark matter detection with
antinuclei.
