Strong anomaly and eta → 3π decay
Description
The amplitude for eta → 3π is calculated in terms of the amplitude for eta' → etaππ using the strong anomaly and the partial conservation of the U(1) current. The isospin violation, an m/sub u/ - m/sub d//m/sub u/ + m/sub d/ effect, is large. The eta' decay constant is estimated from psi → eta'γ. The result for eta → 3π is in good agreement with experiment
