Abstract: The polarization of Xi(0) and Xi(0) hyperons produced by 800 GeV/c protons on a BeO target at a fixed targeting angle of 4.8 mrad is measured by the KTeV experiment at Fermilab. Our result of 9.7% for Xi(0) polarization shows no significant energy dependence when compared to a result obtained at 400 GeV/c production energy and at twice our targeting angle. The polarization of the Xi(0) is measured for the first time and found to be consistent with zero. We also examine the dependence of polarization on production p(t).
