摘要：

We introduce a new concept, the handedness of a jet, which can be used to determine the polarization of a high-energy quark or gluon produced in a hard collision. The method can be tested in e+ e- --> 2 jets at the Z0 peak where the polarization of the emerging quarks is known and correlation between jet handedness and parton polarization could be determined. Subsequently, this correlation could be used in other contexts to determine the parton polarization from a measurement of jet handedness. In particular, the method could be very useful for measuring quark and gluon polarization and the quark "transversity" distribution in the proton.
