Abstract: | Inclusive cross sections are presented for strange-particle production in proton-proton interactions at 19 GeV/c for the pairs and for Λ, Ks0, Σ+, Σ? and Ξ?. The , the KY and the total strange particle cross sections have been found to be 1.40 ± 0.10 mb, 2.69 ± 0.09 mb and 4.23 ± 0.20 mb, respectively. The charged multiplicity distributions for events with Ks0, Λ, or K0 Λ are shown to follow a modified KNO curve, whereas K+ Λ does not. For the inclusive reactions , we find that the average charged multiplicity of the remainder system X++ is the same as when X++ is produced in other reactions with the same system energy and quantum numbers. |
