Аннотация:A new model for pd elastic large-angle scattering based on the intermediate dibaryon resonanceproduction is proposed. Preliminary calculation results for the observables in pd backward scattering based on a simple model including one-nucleon exchange and the intermediate N+\Delta near-threshold state D_{12}(2150) are presented. A sizeable contribution of the dibaryon D_{12}(2150) to pd elastic backward scattering is shown in the energy range 0.3 < T_p < 1 GeV, where the most severe discrepancies between the conventional theoretical approaches and experimental data occur.
