英文摘要The decay psi' + pi(+)pi(-)pi(0) is analyzed using a sample of 14 million psi' events taken with the BESII detector at the BEPC, and the branching fraction is measured to be B(psi' -> pi(+)pi(-)pi(0)) = (18.1 +/- 1.8 +/- 1.9) x 10(-5). A partial wave analysis is carried out using the helicity amplitude method. psi' -> rho(770)pi is observed, and the branching fraction is measured to be B(psi' -> rho(770)pi) = (5.1 +/- 0.7 +/- 1.1) x 10(-5), where the first error is statistical and the second one is systematic. A high mass enhancement with mass around 2.15 GeV/c(2) is also observed. Attributing this enhancement to the p(2150) resonance, the branching fraction is measured to be B(psi' -> rho(2150)pi -> pi(+)pi(-)pi(0)) = (19.4 +/- 2.5(-3.4)(+11.5)) x 10(-5). The results will help in the understanding of the longstanding "rho pi puzzle" between J/psi and psi' hadronic decays. (c) 2005 Elsevier B.V. All rights reserved.
