Abstract
We have measured the polarization of Lambda and <(Lambda)over bar> hyp erons produced by 800 GeV protons on a Be target at a fixed targeting angle of 4.8 mrad. Comparison with previous data at 400 GeV production energy and twice the targeting angle shows no significant energy depe ndence for the Lambda polarization. This is in striking contrast to th e energy dependence found for Sigma(+) and Xi(-) polarizations. We fin d no evidence for <(Lambda)over bar> polarization at 800 GeV.
