Measurement of $\ddot{I}{€}^0\hat{I}›$, ${\bar{K}}^{0}n$, and $\ddot{I}{€}^0\hat{I}{\pounds }^0$ production in $K^{-}p$ interactions for $p_{K^{-}}$ between 514 and 750 MeV/$c$

Abstract

Differential cross sections and hyperon polarizations have been measured for ${\bar{K}}^{0}n$, $\ddot{I}{€}^0\hat{I}›$, and $\ddot{I}{€}^0\hat{I}{\pounds }^0$ production in $K^{-}p$ interactions at eight $K^{-}$ momenta between 514 and 750 MeV/$c$. The experiment detected the multiphoton final states with the Crystal Ball spectrometer using a $K^{-}$ beam from the Alternating Gradient Synchrotron of BNL. The results provide significantly greater precision than the existing data, allowing a detailed reexamination of the excited hyperon states in our energy range.
