ATLAS measured charged-particle production in 9.62 TeV p-O collisions, yielding a fiducial pO cross section of 396 mb and extrapolated p-air inelastic cross section of 406 mb, with distributions an order of magnitude more precise than hadronic model differences.

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.
