An excess of $~ 10–20 GeV$ 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 of solar modulation, the antiproton production cross section, and interstellar cosmic-ray propagation. After accounting for these uncertainties, we confirm the presence of a $4.7σ$ antiproton excess, consistent with that arising from a $$m_χ ≈ 64–88 GeV$$ dark matter particle annihilating to $$\bar{bb}$$ with a cross section of $$σv ≃ (0.8–5.2) × 10^{-26} m^3/s$$. If we allow for the stochastic acceleration of secondary antiprotons in supernova remnants, the data continue to favor a similar range of dark matter models $$(m_χ ≈ 46–94 GeV, σv ≈ (0.7–3.8) × 10^{-26} cm^3/s)$$ with a significance of $3.3σ$. The same range of dark matter models that are favored to explain the antiproton excess can also accommodate the excess of GeV-scale gamma rays observed from the Galactic center.
