Abstract

A study of three-body final states produced in 2-prong ${K}^{\ensuremath{-}}p$ interactions at 4.57 BeV/c is presented on the basis of 10 500 Guts-fitted events. Abundant production of ${K}^{*}(890)$ is observed in all three final states (${K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}n$, ${\ensuremath{\pi}}^{\ensuremath{-}}p{\overline{K}}^{0}$, and ${K}^{\ensuremath{-}}p{\ensuremath{\pi}}^{0}$), while ${K}^{*}(1420)$ is more copiously produced in the final state ${K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}n$ than in the others. The spin density matrix elements for the ${K}^{*}(890)$ and ${K}^{*}(1420)$ are given and the production mechanisms are discussed in terms of the one-meson-exchange model. The cross sections for ${K}^{*}(890)$ and ${K}^{*}(1420)$ are given.
