ReactionsK−d→K¯0π−dandK−d→K¯0π−npsat 5.5 GeV/c

New data are presented on cross sections and angular distributions of resonances produced in the reactions $K^{-}d\to {\overline{K}}^0{\pi }^{-}d$ and $K^{-}d\to {\overline{K}}^0{\pi }^{-}n{p}_s$ at 5.5 GeV/c. The production mechanisms and decay angular distributions are analyzed for the ${\overline{K}}^{*}\mathrm{}\left(890\right)\mathrm{}$, ${\overline{K}}^{*}\mathrm{}\left(1420\right)\mathrm{}$, and $\Delta \mathrm{}\left(1236\right)\mathrm{}$ resonances. The ${\overline{K}}^0{\pi }^{-}n{p}_s$ final state is discussed in terms of the Veneziano $B_5$ model and also using the Van Hove longitudinal-phase-space technique. In addition, a Regge model with absorption is used to describe $\Delta \mathrm{}\left(1236\right)\mathrm{}$ production in the reaction $\overline{K}N\to \overline{K}\Delta \mathrm{}\left(1236\right)\mathrm{}$. The spherical harmonic moments of the ${\overline{K}}^0{\pi }^{-}$ system as a function of $K\pi$ mass are discussed for the reaction $K^{-}d\to {\overline{K}}^0{\pi }^{-}p+\mathrm{MM}$.
