Spin-dependent Fragmentation Functions

Abstract

I will give an overview on fragmentation functions with particular emphasis on spin-dependence. A straightforward classification scheme permits to label all independent fragmentation functions for a given physical situation in an unambiguous way. In the context of light-cone quantisation the leading twist fragmentation functions have an intuitive probabilistic interpretation.
