Description
Inspired by Belle data of $\Lambda$ polarization, the polarized transverse-momentum-dependent fragmentation function (TMD FF) $D_{1T}^\perp$ become a hotspot in both theory and experiments. Several parametrizations of $D_{1T}^\perp$ has been proposed with different assumptions on their flavor dependences. Employing an isospin symmetric framework we studied transverse polarizations of $\Lambda$ in various collisions. Recent measurements of $\Lambda$ polarization in jets by STAR, together with several theoretical progress on nuclear dependences and effective model results, have promoted the research of $D_{1T}^\perp$ to a new phase with more clear knowledge on their flavor structures. We will present our recent progress on this topic.
