Description

By adopting the helicity formalism within a TMD scheme, we present the complete structure of the azimuthal dependences and polarization observables for two-hadron production in $e^+e^-$ annihilation processes. The leading-twist TMD fragmentation functions (FF) for spin-1/2 hadrons, with their properties and their probabilistic interpretation, are fully accounted for.
The role of the polarizing FF is discussed in detail and its extraction from Belle data for the transverse polarization of $\Lambda$'s is shown. Estimates for SIDIS processes at the EIC are presented.
