The AMS-02 collaboration has released preliminary data on the antiproton fraction in cosmic
rays. The surprisingly hard antiproton spectrum at high rigidity has triggered speculations …

Measurements of the cosmic ray antiproton spectrum can be used to search for contributions
from annihilating dark matter and to constrain the dark matter annihilation cross section …

Cosmic-ray antiprotons are a powerful tool for astroparticle physics. While the bulk of
measured antiprotons is consistent with a secondary origin, the precise data of the AMS-02 …

Cosmic ray antiprotons provide a powerful tool to probe dark matter annihilations in our
galaxy. The sensitivity of this important channel is, however, diluted by sizable uncertainties …

The AMS-02 experiment is measuring the cosmic ray antiproton flux with high precision. The
interpretation of the upcoming data requires a thorough understanding of the secondary …

The AMS-02 experiment is measuring the high energy cosmic rays with unprecedented
accuracy. We explore the possibility of determining the cosmic-ray propagation models …

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 …

Global fits of primary and secondary cosmic-ray (CR) fluxes measured by AMS-02 have
great potential to study CR propagation models and search for exotic sources of antimatter …

Using the updated proton and helium fluxes just released by the AMS-02 experiment we
reevaluate the secondary astrophysical antiproton to proton ratio and its uncertainties, and …

The AMS-02 collaboration has published the measurement of the cosmic antiproton to
proton ratio p¯/p and the p¯ flux with a high precision up to∼ 450 GeV. In this work, we …
