摘要：

A study of antiproton annihilation in liquid deuterium into pi(+)pi(-)pi(-) and a spectator proton is presented. For a long time this reaction resisted a description by final state interactions which is surprising (and disturbing) given the success of the final state interaction model in other annihilation reactions. It is shown that the introduction of p(1450) is essential to Set a reasonable description of the measured Dalitz plot. This resonance was never tried in previous attempts to understand this data. A possible isospin-2-pi-pi S-wave contribution was tested, but no evidence was found for such a contribution. (C) 1999 Elsevier Science B.V. All rights reserved.
