Abstract

The cross section for the production of Ξ+ particles in K+p interactions at 12.7 GeV/c is 10 ± 3μb; the Ξ- production cross section is 2.5 ± 1.0 μb; the upper limit on Ω- or Ω+ production is 0.4 μb. The Ξ- are produced preferentially in the backward direction in the CM system while the Ξ+ are produced mainly forward. The mass and lifetime of the Ξ+ agree with the accepted values for the Ξ- hyperon.
