Abstract

We present inclusive ¶ and K*0(892) cross sections and Feynman x-spectra in K+ p collisions at 250 GeV/c. In the K+ fragmentation region, x > 0.2, the ratio of ¶ to K*0(892) is used to estimate the strangeness suppression factor λ, with the result γ=0.17 ± 0.02 (stat ± 0.01 (syst). We see no evidence for an energy dependence of λ in the CM energy range 7.8 ≤ s≤21.7 GeV.
