Spin structure of nucleon and spin transfer in high energy fragmentation process
Zuo-Tang Liang
Abstract
Spin transfer in high energy fragmentation process is determined by the hadronization mechanism and spin structure of hadrons.It can be studied by measuring the polarizations of hyperons and/or vector mesons in e+e- annihilation, in the current fragmentation region of polarized deeply inelastic lN-scatterings, and high pT-jets in polarized pp-collisions.Theoretical calculations have been made using different models.In this talk, I will briefly summarize the main features of the models, the results obtained and the comparison with available data. They can be used for future tests by experiments.
