英文摘要	The implications of the first AMS-02 (p) over bar /p data for the propagation of cosmic rays and the properties of dark matter (DM) are discussed. Using various diffusive re-acceleration (DR) propagation models, one can derive very conservative upper limits on the DM annihilation cross sections. The limits turned out to be compatible with that from the Fermi-LAT gamma-ray data on the dwarf spheroidal satellite galaxies. The flattening of the (p) over bar /p spectrum above similar to 100 GeV in the current data still leaves some room for TeV scale DM particles. More antiproton data at high kinetic energies are needed to constrain the properties of the DM particles.
