Abstract
A study of antiproton annihilation in liquid deuterium into pi(+)pi(-)pi(-) and a spectator proton is presented. For a long time this reaction resiste d a description by final state interactions which is surprising (and distur bing) given the success of the final state interaction model in other annih ilation reactions. It is shown that the introduction of p(1450) is essentia l to Set a reasonable description of the measured Dalitz plot. This resonan ce 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 .
