Ξ− and Ω− polarization from a neutral hyperon beam

Results from Fermilab experiment E‐800 on the polarization of the Θ‐ and Ω‐ produced from polarized and unpolarized neutral hyperon beams. Two methods were used to produce the Θ‐ and Ω‐ particles. One method used polarized neutral hyperon beam produced from 800 GeV protons incident on a Beryllium target which was then spin transfer polarized. The second method used unpolarized neutral hyperon beams, neutral production mode. These methods are described and the polarizations determined are presented. (AIP)
