A robust excess in the cosmic-ray antiproton spectrum: Implications for annihilating dark matter
A robust excess in the cosmic-ray antiproton spectrum: Implications for annihilating dark matter
An excess of $\ensuremath{\sim}10--20\text{ }\text{ }\mathrm{GeV}$ cosmic-ray antiprotons has been identified in the spectrum reported by the AMS-02 Collaboration. The systematic uncertainties associated with this signal, however, have made it difficult to interpret these results. In this paper, we revisit the uncertainties associated with the time, charge and energy-dependent effects …
