The production of K S 0 , Λ and Λ is measured in π + p reactions at 16 GeV/ c . The total strange particle cross section is found to be 4.0 ± 0.3 mb, about 20% of the inelastic cross section. Cross sections for single strange particles and for strange particle pairs are determined, both inclusively and as functions of the charged multiplicity. Relative production rates for different strange particle combinations are compared with the prediction of the isospin statistical model. Inclusive spectra for single particles are studied and it is found the K S 0 are produced mostly in the forward hemisphere, most probably by fragmentation of the incident pion into K K π . The Λ are mostly backwards, probably deriving from fragmentation of the proton into ΛK pairs. The Λ tend to be produced forwards, but evidence is found for central Λ Λ production. Distributions in rapidity of the Λ particles from π + p interactions are compared in terms of the factorisation hypothesis. Results are given on the Λ transversal polarisation.

Inclusive cross sections and one-particle inclusive spectra are given for neutral K, Λ and Λ produced in K − p and K + p interactions at 32 GeV/ c in the 4.5 m Mirabelle hydrogen bubble chamber at the Serpukhov accelerator. Cross sections for associated production are also given, and the energy dependences of the cross sections and of the x distributions in the central and in the fragmentation regions are discussed.

Inclusive pi0 Production in pi- p Interactions at 5-GeV/c

We have measured the cross section for the reaction π−p→π0+anything at an incident momentum of 5 GeV/c. The two γ rays from π0 decays were detected using a 150-element lead-glass hodoscope array. A comparison is given of the inclusive π0 spectrum from hydrogen (obtained through a subtraction of CH2 and C target data) with π0 production from C and Cu.
