Analysis of some multiparticle final states produced in K−-proton interactions at 6 GeV/c☆

The reactions K−p→pKoπ+π−π−, pKoπ+π−π− πo and nKoπ+π+π−π− have been studied at 6 GeV/c incident momentum. Cross sections are given for the various resonances produced in each channel. In the first two channels, resonance production dominates. A detailed analysis has been performed on the simultaneous resonance production K−p→ Δ++K∗−π−, and evidence is given for a vector-ex-change mechanism. A Veneziano-model calculation has been attempted for this quasi three-body final state, and the predictions are found to be in good agreement with the experimental results.
