The existence of the -, a baryon of mass 1676 MeV and strangeness -3, has been predicted from SU(3) invariance of the strong interactions. This prediction was beautifully confirmed by three examples found in the 80-in. hydrogen bubble chamber in a separated 5.0 BeV/c K beam at the AGS accelerator at Brookhaven National Laboratory. We have found another example of an , which decays into a and o. The three previous examples have exhibited the decay modes and K (two examples).
The exposure for this experiment was carried out at Brookhaven National Laboratory using the 80-in. hydrogen bubble chamber. A mass-separated beam of 4.2 BeV/c K mesons from the AGS was incident on the bubble chamber. We have scanned 25000 pictures for events initiated by an incident-beam track and containing at least two (charged or neutral) V particles. (Extracted from the introductory part of the paper.).
