Study of the reactions ${\overline{K}}^{0}p\to \Lambda {\pi }^{+}$ and ${\overline{K}}^{0}p\to {\Sigma }^0{\pi }^{+}$ from 1 to 12 GeV/c

Cross sections, differential cross sections, and hyperon polarization results are presented for the reactions ${\overline{K}}^{0}p\to \Lambda {\pi }^{+}$ and ${\overline{K}}^{0}p\to {\Sigma }^0{\pi }^{+}$ in the momentum interval 1 to 12 GeV/c. Emphasis is placed on the comparison of $\Lambda$ and $\Sigma$ channels, and on the momentum dependences of the data. In particular, the $\Lambda$ polarization data are consistent with being independent of energy above 2 GeV/c; and the slopes of the forward cross sections are found to increase toward the slope values for the line-reversed reactions $\pi p\to K(\Lambda ,\Sigma )$ as energy increases.
