摘要：

The polarization of 103211 OMEGA- hyperons produced in 800 GeV proton-beryllium inclusive reactions has been measured. Between 0.3 < x(F) < 0.7 and 0.5 < p(t) < 1.3 GeV/c, the OMEGA- polarization is found to be consistent with zero, with a mean value of -0.01 +/- 0.01 at [x(F)]-0.5 and [p(t)] = 0.95 GeV/c. This behavior is similar to that of LAMDA0BAR, which also does not have any quarks in common with the incident proton, but is different from XI+BAR, which is significantly polarized in the same kinematic region.
