The spin polarization of lambda hyperons exhibits an anisotropic alignment with the total orbital angular momentum of the collision system, serving as a probe for vorticity in the strongly interacting matter. We study the lambda hyperon decay into proton-pion pair to measure global polarization in heavy-ion collisions, adopting an approach previously used by the STAR Collaboration to investigate the vortical structure of the produced medium. This method is now applied to Xe + Xe collisions at a center-of-mass energy of 2.87 GeV per nucleon pair, generated with the UrQMD model. The results provide a baseline for future experimental measurements with the MPD detector.
