Inspire Record 158991 DOI 10.17182/hepdata.34497

We present a study of the reactions p p → p p π 0 , p p → p n π + , and p p → n p π − at 8.8 GeV/ c . Cross sections for the reactions are given, and the main features of the data are shown. The data are compared with the predictions of the Deck model, and evidence is presented for the presence of baryon exchange in the Deck amplitude.

EXCLUSIVE ANNIHILATION PROCESSES IN 8.8-GEV ANTI-P P INTERACTIONS AND COMPARISONS BETWEEN ANTI-P P NONANNIHILATIONS AND P P INTERACTIONS

We give cross sections for annihilation and non-annihilation reactions in p p interactions at 8.8 GeV. The non-annihilation data are compared with pp data from the same experiment. We compare data on resonance production and on the impact parameter structure of the final states in p p annihilation and non-annihilation and pp interactions. We investigate the charge structure of the 2 π + 2 π − π 0 final state, and find it consistent with a simple quark model.
