摘要：

We show in the context of perturbative QCD that all single transverse vector polarizations or analyzing powers are zero in the high-momentum-transfer limit. The proof depends on hadron helicity conservation, which applies to exclusive processes that are dominated by a short-distance reaction mechanism. Some comments are made about the available data.
