Polarization of Hyperons Produced by Meson Beams

The work is devoted to the transverse polarization (\(P_{N}\)) of \(\Lambda\)-hyperons and corresponding antihyperons produced in meson–proton and meson–nuclear interactions in inclusive reactions. The currently available experimental data are compared with calculations based on the chromomagnetic polarization of quark (CPQ) model. The main features of the CPQ model are the prediction of hyperon polarization oscillations depending on the Feynman variable \(x_{F}\) in the case of a sufficiently strong chomomagnetic field and resonant dependence of the polarization on the c.m. energy (\(\sqrt{s}\)) for some reactions. Calculations based on the CPQ model were performed for still unexplored kinematic regions and various targets and can be tested in the SPASCHARM experiment at the NRC ‘‘Kurchatov Institute’’—IHEP.
