AMS-02 antiprotons from annihilating or decaying dark matter

Recently the AMS-02 experiment reported an excess of cosmic ray antiprotons over the expected astrophysical background.We interpret the excess as a signal from annihilating or decaying dark matter and find that the observed spectrum is well fitted Gift Cards and Tags by adding contributions from the annihilation or decay of dark matter with mass of O(TeV) or larger.Interestingly, Wino dark matter with mass of around 3 TeV, whose thermal relic abundance Lighting Incandescent is consistent with present dark matter abundance, can explain the antiproton excess.We also discuss the implications for the decaying gravitino dark matter with R-parity violation.
