摘要：

Polarization properties of strange baryons produced in pp reactions, p + p --> p + Lambdadegrees + K+ and p + p --> p + Sigmadegrees + K+, near thresholds of the final states pLambdadegreesK(+) and pSigmadegreesK(+) are analysed relative to polarizations of colliding protons. The cross-sections for pp reactions are calculated within the effective Lagrangian approach accounting for strong pp rescattering in the initial state of colliding protons with a dominant contribution of the one-pion exchange and strong final-state interaction of daughter hadrons.
