    Abstract:
    We report measurements of the inclusive transverse momentum (p T ) distribution of centrally produced KS0, K ± (892), and φ0(1020) mesons up to p T =10 GeV/c in minimum bias events, and KS0 and Λ0 particles up to p T =20 GeV/c in jets with transverse energy between 25 and 160 GeV in pp̄ collisions. The data were taken with the CDF II detector at the Fermilab Tevatron at √s=1.96 TeV. We find that as p T increases, the p T slopes of the three mesons (KS0, K ± , and φ) are similar. And using our previous Λ0 results from minimum bias events, we show that the ratio of Λ0 to KS0 as a function of p T in minimum bias events becomes similar to the fairly constant ratio in jets at p T ∼5 GeV/c. This suggests that the particles with p T ≠3 5 GeV/c in minimum bias events are from "soft" jets, and that the p T slope of particles in jets is insensitive to light quark flavor (u, d, or s) and to the number of valence quarks. We also find that for p T ≠2 4 GeV relatively more Λ0 baryons are produced in minimum bias events than in jets. © 2013 American Physical Society.
