Abstract

Jets produced in association with a Z0Z^{0} or W±W^{\pm} boson in hadronic collisions are automatically polarized due to the parity violation of weak interaction, making these processes ideal for understanding the spin transfer from polarized partons to polarized hadrons. Furthermore, leveraging this feature, we can also employ the weak-boson-tagged process to study the quenching phenomenon of polarized jets, an aspect that has rarely been discussed in the literature. In this work, we compute the polarization of Λ\Lambda hyperons in pppp collisions and investigate the nuclear modification due to the jet-medium interaction in AAAA collisions. Our results highlight this process as a valuable probe of polarized parton hadronization and of spin-dependent medium effects in the QGP.
