Analysing powers and differential cross sections for p p → π − π + and p p → K − K + have been measured over the full angular range using a polarised target at LEAR at 20 beam momenta from 360 to 1550 MeV/ c . Discrepancies in the normalisation of earlier d σ/ d Ω data at low momenta are clarified. Above 1000 MeV/ c , A 0N results confirm values close to +1 over most of the angular range for both reactions, in excellent agreement with earlier data of lower statistics. Below 1000 MeV/ c , where the analysing power is measured for the first time, large variations of A 0N with energy and angle are present.

STRANGE PARTICLE PRODUCTION IN ANTI-P P ANNIHILATIONS AT 8.8-GEV/C

Hill, J.C. ; Ansorge, R.E. ; Carter, J.R. ; et al.

Results are presented from an experiment at the SLAC 40″ hybrid facility (SHF) using an 8.8 GeV/ c antiproton beam. Using external detectors and an on-line trigger, a sample of events enriched in p p annihilations was obtained. pp interactions taken under the same conditions enabled the annihilations to be identified. Cross sections and distributions for the inclusive production of K s 0 and K ∗± (890), and cross sections for exclusive channels with a pair of strange particles are presented.
