We investigate the reaction e+e- → 3π that can be described by the anomalous part of an effective chiral lagrangian. We calculate the next-to-leading corrections to the process and make an estimate of all-order correction within a specific chiral model of pseudoscalars and vector resonances. Our final results describe the process from threshold to the omega resonance in terms of a single parameter. © 1991.
