A Study of the Reactions $K^0_L p \to K^0_S p$, $\Lambda \pi^+$, $\Sigma^0 \pi^+$ and $\Lambda \pi^+ \pi^0$ Near 550-{MeV}/$c$

We present measurements of the differential and polarization cross sections for the reactions KL0p→Ks0p, Λπ+, Σ0π+, and Λπ+π0 made in a hydrogen bubble chamber exposed to a beam of KL0 with incident momentum 550±35 MeV/c. The quasielastic data imposes additional constraints on the partial-wave analyses of the KN and K¯N systems. Our data show no strong energy-dependent effects in the region of the reported Σ(1580), JP=32− state. The phase of the forward regeneration amplitude was found to be about - 160° independent of KL0 momentum.

The asymmetry ratioA = (σ⊥ -σ∥)/(σ⊥ +σ∥) has been measured by means of linearly polarized γ-rays for π0 and π+ photoproduction. For the reaction γ + p → n + π+, measurements were taken for θc.m. = 135° at γ-ray energies ranging from 390 to 909 MeV. For the reaction γ + p → p + π0, measurements were taken for θc.m. = 60° and 90° at γ-ray energies ranging from 426 to 918 Mev.
