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 p_t=1.01 GeV/c and x_f=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<p_t<1.14 GeV/c and 0.42<x_f<0.62. The average Λ polarization is found to be -0.188±0.024, consistent with previous results.
