The precise knowledge of fragmentation functions is necessary for our understanding of hard scattering processes where particles in the final state are detected in terms of factorized pQCD cross-sections.
Studying electron-positron annihilation provides the cleanest access to fragmentation functions. In particular, our knowledge of polarization dependent fragmentation functions have...

Fragmentation functions, describing the formation of hadrons from partons, are an indispensable tool in the interpretation of hadron-production data, e.g., in the investigation of nucleon structure via semi-inclusive deep-inelastic scattering. The cleanest process to access fragmentation functions is hadron production in electron-positron annihilation. However, little information can be...

We present our calculations of the polarization- and transverse momentum dependent single hadron fragmentation functions (FF) and dihadron fragmentation functions (DiFF) using the most recent quark-jet model. In this extension of the model the complete description of a polarized quark state after each step of hadron formation was given, based on a self-consistent treatment of the quark...

I review the current status of the determination of the collinear helicity and transversity parton distribution functions from a global QCD analysis of experimental measurements. I highlight the most recent achievements and outline the open issues to be addressed in the future.
