Study of the reactions $K_L^{0}p\to K_s^{0}p, \Lambda {\pi }^{+}, {\Sigma }^0{\pi }^{+}, \mathrm{and} \Lambda {\pi }^{+}{\pi }^0$ near 550 MeV/c

We present measurements of the differential and polarization cross sections for the reactions $K_L^{0}p\to K_s^{0}p, \Lambda {\pi }^{+}, {\Sigma }^0{\pi }^{+}, \mathrm{and} \Lambda {\pi }^{+}{\pi }^0$ made in a hydrogen bubble chamber exposed to a beam of $K_L^0$ with incident momentum 550±35 MeV/c. The quasielastic data imposes additional constraints on the partial-wave analyses of the $\mathrm{KN}$ and $\overline{K}N$ systems. Our data show no strong energy-dependent effects in the region of the reported $\Sigma \mathrm{}\left(1580\right)\mathrm{}$, $J^P=\frac{3}{2^{-}}$ state. The phase of the forward regeneration amplitude was found to be about - 160° independent of $K_L^0$ momentum.
