Summary

Description
English: Discovery of the very first Omega minus at BNL in 1964. Adapted from original tracing. The tracks of neutral particles (dashed lines) are not visible in the bubble chamber. .The collison of a K- meson with a proton creates an Ω−, a K0 and a K+. The Ω− decays into a π- and a Ξ0, which in turn decays into a Λ0 and a π0. The Λ0 decays into a proton and a π−. The π0, invisible due to its short lifetime, decays into two photons (γ), which in turn each create an electron-positron pair.
