Abstract

We report the first polarization transfer measurements for exclusive hyperon production reactions. The normal spin transfer coefficient D_NN for ^→pp → pK⁺ ^→Λ is large and negative for forward Λ production at a beam momentum of 3.67GeV/c, a result qualitatively consistent with expectations for a mechanism dominated by kaon exchange and rescattering. The sign of D_NN is opposite to that observed in the fragmentation regime for inclusive Λ production at much higher energies.
