We calculate the contribution to the polarization.ofhyperons in relativistic nuclear collisions at high energy.from the decays of.∗.(1385) and0,which are the predominant.sources ofproduction besides the primary component,.as a function of the momentum. Particularly, we estimate.the longitudinal component of themean spin vector as a function.of the azimuthal angle in the transverse plane, assuming.that primary .∗ and 0 polarization follow the predictions.of local thermodynamic equilibrium in a relativistic fluid..Provided that the rapidity dependence around midrapidity of.polarization is negligible, we find that this component of the.overall spin vector has a very similar pattern to the primary.one. Therefore, we conclude that the secondary decays cannot.account for the discrepancy in sign between experimental.data and hydrodynamic model predictions of the longitudinal.polarization of hyperons recently measured by the STAR.experiment at RHIC.
