The reaction p p -> p p pi+ pi- at 7.9 BeV/c
… body final state N*++ p pi-. A simple one pion exchange model is compared to the data and is shown to give gene'ra11y good results for invariant mass distributions for the entire final state, and for mass and angular distributions for the quasi-three body state. Discrepancies between the …

Strange-particle production in 8 BeV/c proton-proton interactions
… mass in the K+P J\ final state. The simple one pion exchange model does not seem to predi.ct adequately the distribution observed. The OEEM also predicts a cross section for this final state a factor of 2 larger than the measured value of 54 ± 7 ~b if no cutoff in 4-momentum transfer to the …
