Abstract

The polarization of 103 211 - hyperons produced in 800 GeV proton-beryllium inclusive reactions has been measured. Between 0.3<xF<0.7 and 0.5<pt<1.3 GeV/c, the - polarization is found to be consistent with zero, with a mean value of -0.010.01 at xF=0.5 and pt=0.95 GeV/c. This behavior is similar to that of 0, which also does not have any quarks in common with the incident proton, but is different from +, which is significantly polarized in the same kinematic region.
