Chiral quark filtering mechanism of hyperon polarization

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 -hyperon polarization and derive its linear xF-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.
