Asymmetries in the production of Λ0, Ξ−, and Ω− hyperons in 500 GeV/cπ−–nucleon interactions
2000
Using data from Fermilab fixed-target experiment E791, we have measured particle–antiparticle production asymmetries for Λ0, Ξ−, and Ω− hyperons in π−–nucleon interactions at 500 GeV/c. The asymmetries are measured as functions of Feynman-x (xF) and pT2 over the ranges −0.12⩽xF⩽0.12 and 0⩽pT2⩽4 (GeV/c)2. We find substantial asymmetries, even at xF=0. We also observe leading-particle-type asymmetries which qualitatively agree with theoretical predictions.
