摘要：

The dominant decay mode of the eta,eta' --> etapipi, is investigated within the framework of infrared regularized U(3) chiral perturbation theory up to fourth chiral order and including one-loop corrections. We find reasonable agreement with experimental data and observe convergence of the chiral series. (C) 2002 Elsevier Science B.V. All rights reserved.
