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 p s 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 Białas and Zalewski obtained from the quark model. The final state K − π + Δ −(1236) is analyzed by use of the Van Hove plot.
