Description

The fragmentation function of an unpolarized quark into a noncollinear hadron may depend on the hadron spin and transverse momentum, kperpendicular. The data on the polarization of Λ,Λ-bar baryons inclusively produced in unpolarized p-N processes are used to determine a simple phenomenological expression for this new 'polarizing fragmentation function', which describes remarkably well the experiments. More details can be found in the paper hep-ph//0008186 (Phys. Rev. D, in press), and in the talk by M. Anselmino in these Proceedings
