Abstract: Mechanisms for the production of S-1(0) diproton pairs, {pp}(s), in the pd ->{pp}(s)n reaction are studied at proton beam energies 0.5-2 GeV in kinematics similar to those of backward elastic pd scattering. This reaction provides valuable information on the short-range NN and pd interactions that is complementary to that investigated in the well-known pd -> dp and dp -> p(0(degrees))X processes. The pd ->{pp}(s)n reaction is related to the subprocesses pi(0)d -> pn and pN ->{pp}(s)pi using two different one-pion-exchange (OPE) diagrams. Within both these models a reasonable agreement could be obtained with the data below 1 GeV. The similar energy dependence of the pd ->{pp}(s)n and pd -> dp cross sections and the small ratio of about 1.5% in the production of {pp}(s) to deuteron final states follow naturally within the OPE models.
