Updated predictions for cosmic antinuclei fluxes from dark matter yield tighter upper limits on light DM annihilation cross sections from AMS-02 antiproton data and show that GAPS could improve those limits by up to an order of magnitude below 50 GeV.
NLO perturbative QCD calculations predict only a mild few-percent excess of antineutrons over antiprotons in pp collisions, not supporting the ~30% excess reported by NA49.
