摘要：

We apply the picture proposed in a recent Letter for transverse hyperon polarization in unpolarized hadron-hadron collisions to the exclusive process e(-)p-->e(-)HK such as e(-)p-->e(-)LambdaK(+), e(-)p-->e(-)Sigma(+)K(0), or e(-)p-->e(-)Sigma(0)K(+), or the similar process e(-)p-->e(-)npi(+) with longitudinally polarized electron beams. We present the predictions for the longitudinal polarizations of the hyperons or neutron in these reactions, which can be used as further tests of the picture.
