Production ofΩ−Hyperons inK−pInteractions at 5.5 GeV/c

Abstract

The results of a search for ${\Omega }^{-}$ hyperon production and decay in $K^{-}p$ interactions at 5.5-GeV/c $K^{-}$ momentum are presented. Three unambiguous examples of ${\Omega }^{-}$ production were found, and the mass of the ${\Omega }^{-}$ was measured. The mass value obtained is 1671.8±0.9 MeV/${\mathit{c}}^2$. Other details of the three events are given.
