The reactions p p → Λ Λ, Λ Σ 0 or Σ 0 Λ, Σ + Σ + are studied at an incident momentum of 3.6 GeV/ c in a 35.4 event/μb experiment performed in the CERN 2m HBC. Total and differential cross sections are presented. The polarization of the hyperons is measured as a function of t and for the reaction p p → Λ Λ the complete spin correlation matrix is given.

Observation of the *forbidden* double charge exchange reaction anti-p p ---> antisigma- sigma- at 3.6 gev/c

Data are presented which firmly establish the existence of the double charge exchange reaction p p → Σ − Σ − at 3.6 GeV/ c . The forward cross section was found to be (5.9 ± 1.1) μb and the ratio of the “forbidden” to “allowed” forward cross section is R = σ( Σ − Σ − σ( Σ + Σ + ) = 0.09 ± 0.02 .
