Lambda and Lambda-bar polarization as a measurement of distribution and fragmentation functions

Abstract

A combined analysis of the polarization vector of the Lambda baryons produced in DIS processes may give a relevant insight of the hadronization process which governs the transition from partons to physical hadrons and precise indications on the mechanisms of $spin$ transfer from partons to hadrons. We give here a short review of some interesting results.
