ChargedΣHyperons from 1001K−Meson Stars

1001 $K^{-}$-meson stars were found by area-scanning in four successive stacks of emulsion pellicles exposed to momentum-analyzed negative channels at the Berkeley Bevatron. Systematic following of the prongs showed that there emerged from these stars 319 charged $\pi$ mesons, 46 hyperfragments, and 158 identified charged hyperons. There were 26 ${\Sigma }^{+}\to p+{\pi }^0$ decays at rest; 20 ${\Sigma }^{+}\to {\pi }^{+}+n$ decays at rest; 14 ${\Sigma }^{+}\to p+{\pi }^0$ decays in flight; 26 ${\Sigma }^{\pm }\to {\pi }^{\pm }+n$ decays in flight; 50 ${\Sigma }^{-}$ stars at rest, and 22 ${\Sigma }^{-}$ zero-prong stars with Auger electrons.
