Le résumé fourni par la source

Based on a novel method for producing antineutrons via J / ψ decays, we report a study of n ¯ p inelastic scattering into final states containing kaons. The analysis uses ( 10 087 ± 44 ) × 10 6 J / ψ events collected at the BESIII detector operating at the BEPCII storage ring. Antineutrons are produced via J / ψ → p π − n ¯ decays and tagged by the detected protons and pions, resulting in antineutron momenta ranging from 0 to 1174 MeV / c , while target protons are provided by the hydrogen in the beam-pipe material. The flux-averaged cross sections of the reactions n ¯ p → K + K − π + and n ¯ p → K + K − π + π 0 over this antineutron momentum spectrum are measured to be 0.53 − 0.12 + 0.15 ± 0.08 mb and 1.09 − 0.30 + 0.36 ± 0.31 mb , respectively, where the first uncertainties are statistical and the second are systematic. Due to limited statistics, the contributions of intermediate states remain speculative. The observation of clean antineutron-proton scattering candidates indicates the potential of this approach for future investigations of antineutron-proton interactions.
