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.

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.
Upgraded LHCb muon detector maintains >90% efficiency and sub-percent hadron misidentification in Run 3's higher luminosity via hit pattern analysis.
