Description
At transverse momenta of typical 20 to 40 GeV/c the hard scattering of quarks leads to partially polarized jets. The responsable mechanisms are W+- and Z0 exchange and their interference with gluon exchange. For the jet fragmentation we employ a model with favoured and disfavoured fragmentation according to broken SU(6). For vector mesons and Λ particles a modest polarization is predicted of the order up to approx. 8%. (orig.)
