O ct 2 00 1 On polarization of strange baryons in reactions p + p → p + Λ 0 + K + and p + p → p + Σ 0 + K + near thresholds

Polarization properties of strange baryons produced in pp reactions, p + p → p + Λ0 + K+ and p + p → p + Σ0 + K+, near thresholds of the final states pΛ0K+ and pΣ0K+ 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 (Eur. Phys. J. A 9, 425 (2000)). E–mail: [email protected] E–mail: [email protected], Physics Department, University of Arizona, Tucson, Arizona 85721, USA 1
