Description
Experimental data from Belle Collaboration for the transverse polarization of $\Lambda$'s measured in $e^+e^-$ annihilation processes are used to extract the polarizing fragmentation function (FF) within a TMD approach.
We consider both associated and inclusive $\Lambda$ production, showing a quite consistent scenario. Good separation in flavor is obtained, with four independent FFs. Predictions for SIDIS processes at EIC, crucial for understanding their universality and evolution properties, are also presented.
