Differential cross sections for the reactionsK−p→K¯0n,K−p→K¯0Δ0, andK+p→K0Δ++at 13 GeV/c

Differential cross sections for the reactions $K^{-}p\to {\overline{K}}^{0}n$, $K^{-}p\to {\overline{K}}^0{\Delta }^0$, and $K^{+}p\to K^0{\Delta }^{++}$ in the region $0<\mathrm{}\left|t\right|\mathrm{}<1.2$ ${\mathrm{GeV}}^2$ are presented from a wire-spark-chamber spectrometer experiment performed in a 13-GeV/c separated beam. The results are based on 20 000 ${\Delta }^{++}$ events, 4600 ${\Delta }^0$ events, and 8500 $n$ events. The line-reversed pair of $\Delta$ reactions is used to test Regge exchange degeneracy and an SU(3) sum rule. The energy dependence of all three reactions is studied by comparison with other experiments.
