| Abstract: | New results on inclusive lambda polarization in K?p interactions at 14.3 GeV/c are presented. At the kaon fragmentation vertex, the polarization is compared to that from inclusive experiments at lower momenta and to that from two-body reactions with a Λ. As predicted by the triple-Regge model with Nα (or Nγ) exchange, the polarization is found to be independent of s and MX2/s. In particular it has the same value as that found in the two-body reactions. |
