Additional condition for a role of pion-nucleon rescattering in pd annihilation
Voronov D. V. , Kolybasov V. M.
The distribution with respect to invariant mass of the rrp system is studied as an additional condition on the reaction mechanism for the most interesting channel for the annihilation of stopped antiprotons with deuterium, namely, ρά-^ρ^2π+3π~. For events with momenta of the spectator proton above 200 MeV/c, a clearly defined Δ-resonance peak should be observed.
