Abstract: (Elsevier)

We show that for incident pion momentum p_l_a_b=903MeV/c the cross section of @p^+d->@hpp with the @h produced in the backward direction is very sensitive to the low-energy @hN amplitude. We conclude that the measurement of this reaction at these kinematic conditions will allow a better determination of the @hN scattering length, which is known with a large uncertainty and attracts intense experimental and theoretical interest. Our result strongly motivates performing this experiment in the K1.8BR beam line area at the J-PARC facility in Japan. The experiment will eventually provide new insight on the important quest for eta-mesic nucleus in hadronic physics.
