Abstract:

We study the polarizations and the analyzing powers in high energy inclusive hadron reactions based on the quark recombination (QRC) mechanism. The QRC model reproduces the empirical rule of DeGrand and Miettinen with a relativistic description for the parton-parton interaction. We apply the QRC model to the polarizations of various hadron production processes and demonstrate its success by comparing with experiment. We discuss the importance of relativistic effects in the formulation of the quark recombination process and their significance with regard to spin polarization phenomena in hadron reactions together with quark momentum distributions in hadrons.
