Abstract

The polarization of Σ0 hyperons produced in an inclusive reactons hasbeen measured for the first time. From a sample of 11 000 events produced by 28.5 GeV/c ptorons in the reaction p+Be→Σ0+X, the Σ0 polarization has a value of +0.28±0.13 at pt=1.01 GeV/c and xf=0.60. The polarization of 53 000 Λ hyperons produced from 28.5 Gev/c protons inthe reaction p+Be→Λ+X has been measured in the kinematic range 0.64<pt<1.14 GeV/c and 0.42<xf<0.62. The average Λ polarization is found to be -0.188±0.024, consistent with previous results.
