Abstract

We discuss interplay of the scalar and vector diquarks which decide the characteristics of the spin polarization as functions of p_T and x_F in the wide kinematical range. We demonstrate a significant effect of quark masses on the pair-creation probabilities from vacuum in pp → Σ^- X and γp → ΛX collisions, and also a remarkable correction induced by the diquark form factor in Σ^- p → ΛX collision.
