Strange Particle Production and s - quark Asymmetry

Using hadronic 2° decays recorded by the SLD experiment at SLAC, we have studied the production of strange particles as a function of momentum. A high-purity sample of K ~ was tagged using Cherenkov Ring Imaging Detector(CRID). The #, A and K. were reconstructed in the K+ K-, pm and ~+ T – modes respectively, and CRID identification of K+ and p was used to obtain pure samples of@ and A. We have used the high electron-beam polarisation delivered by the SLC to measure the left-right forward-backward production asymmetries of these particles, and discuss the relationship of these quantities to the underlying strange quark asymmetry in 2° decays.
