Abstract

The model combined with unitarity and impact parameter picture provide a rather simple mechanism of hyperon polarization generation in collision of unpolarized hadrons. We concentrate on a particular problem of Λ-hyperon polarization and derive its linear x_F-dependence as well as its energy and transverse momentum independence at large p_⊥. Mechanism responsible for the single--spin asymmetries in pion production is also discussed.
