Transverse polarization of Lambda hyperons in hadronic collisions

The transverse polarization of hyperon within reconstructed jets in hadronic collisions offers a complementary platform to probe the polarized fragmentation function D₁ₓ^. We illustrate that by performing a global analysis of the transverse polarization of hyperons produced in different kinematic regions and in different hadronic collisions, such as pp, p p, pA, and A collisions, we can pin down the flavor dependence of D₁ₓ^ which has been poorly constrained. Besides the single inclusive jet production, the /Z⁰-boson associated jet production supplements with more capability in removing ambiguities in the flavor dependence of D₁ₓ^.
