Transverse polarization of Lambda hyperons in hadronic collisions

The transverse polarization of Λ hyperon within reconstructed jets in hadronic collisions offers a complementary platform to probe the polarized fragmentation function D1T^⊥. We illustrate that by performing a global analysis of the transverse polarization of Λ hyperons produced in different kinematic regions and in different hadronic collisions, such as $pp$, p p, $pA$, and γ A collisions, we can pin down the flavor dependence of D1T^⊥ which has been poorly constrained. Besides the single inclusive jet production, the γ/Z⁰-boson associated jet production supplements with more capability in removing ambiguities in the flavor dependence of D1T^⊥.
