Hyperon polarization asymmetry: Polarized beams andΩ−production

The parton recombination model relates polarizations in inclusive baryon fragmentation to those of the underlying constituent subprocesses. Measurements of spin-spin correlations in experiments using polarized beams will provide detailed information on the quark spin dynamics in the color-confining recombination process. We present a large number of predictions for the octet baryon→octet baryon transitions. We discuss the production of polarized ${\Omega }^{\mathrm{-}}$’s, required to measure the magnetic moment of the ${\Omega }^{\mathrm{-}}$. We also review the data from unpolarized beam experiments, and find very satisfactory agreement between experiment and theory.
