dc.descriptionA new mechanism for single spin asymmetries in strong interaction is proposed. It is based on instanton-induced nonperturbative chromomagnetic quark-gluon interaction. We estimate the contribution of this interaction to single spin asymmetry in quark-quark scattering. It is shown, that interference between quark spin-flip amplitude induced by instantons and spin-nonflip amplitude, which is related to nonperturbative two gluon exchange, gives a large value for a single spin asymmetry. Due to strong increasing of the instanton-induced spin-flip amplitude with energy, this asymmetry does not vanish at high energies.
