High-momentum-transfer processes with polarized deuterons

On the basis of the nuclear core hypothesis we predict that cross sections for high-energy (e, e'), e, (e'N), (h, N) inclusive reactions and the cross section for the high-momentum-transfer e+D -> e+N+N reaction off polarized deuterons should strongly depend on the deuteron polarization in the kinematics forbidden for the scattering off a free nucleon. A problem of the polarized deuteron structure function extraction from e vectorD vector data is analysed. We demonstrate also that the measurement of the D+N -> p vector+X reaction is sufficient to reconstruct the spin-density matrix of a rapid deuteron. On the basis of the perturbative QCD the rule of the minimal change of helicity for leading hadron production in high-energy inclusive hadron processes is suggested. (orig.)
