Study of K−π− scattering using the reaction K−d → K−π−pps☆

Abstract Approximately 700 events of the reaction K−d → K−π−pps produced by 5.5 GeV/c kaons were used to measure the cross section for Kπ elastic scattering in the T = 3 2 state by a Chew-Low extrapolation. The cross section does not exceed 2.1 mb and has no structure for Kπ masses from threshold up to 2.0 GeV.

Production of the K−π+π−n final state in K−d interactions at 5.5 GeV/c

Abstract The reaction K−d → K−π+π−n ps was studied in a bubble chamber experiment. The cross section was measured to be 1.3 ± 0.2 mb. The final state is dominated by K ∗0 (890) , K ∗0 (1420) and Δ − (1236) production. Partial cross sections, differential cross sections and decay angular distributions of the K ∗0 (890) δ − (1236) final state were found to give good agreement with the predictions of Bialas and Zalewski obtained from the quark model. The final state K−π+Δ−(1236) is analyzed by use of the Van Hove plot.

Search for exotic meson and hyperon final states in K-d interactions at 5.5 Gev/c

Abstract A search has been made for exotic states produced in K − d interactions at 5.5 GeV/ c . The reactions investigated were: K − d→X −− pp, K − d → Y ∗−− π + p and K − d→ M −− Σ + p. Upper limits are set for the production cross sections.
