Abstract

We have carried out a partial-wave analysis (PWA) of three-pion systems produced in the coherent dissociation of + mesons on nuclear targets. The data have been analyzed for copper and lead targets at an incident + energy of 202.5 GeV. This PWA provides further evidence for resonant contributions to JP=1+ and 0- waves at 3 masses below 1.5 GeV, which can be plausibly identified with A1 and mesons. The contribution from electromagnetic production of the A2 has also been extracted, and an estimate for Coulomb production and radiative width of the A1 has been obtained.
