Spin transfer and polarization of antihyperons in lepton induced reactions

Abstract

We study the polarization of antihyperon in lepton induced reactions such as $e^{+}{e}^{-}\to \bar{H}+X$ and $l+p\to l^{\prime }+\bar{H}+X$ with polarized beams using different models for spin transfer in high energy fragmentation processes. We compare the results with the available data and those for hyperons. We make predictions for future experiments.
