The eta->pi^0 pi^0 gamma gamma decay in generalized chiral perturbation theory

Abstract

Calculations of eta->pi^0 pi^0 gamma gamma decay in generalized chiral perturbation theory are presented. Tree level and some of next-to-leading corrections are involved. Sensitivity to the deviations from the standard chiral perturbation theory is discussed.
