摘要：

We investigate the rare radiative eta decay modes eta-->pi(+)pi(-) pi(-)gamma gamma and eta-->pi(0) pi(0) gamma gamma within the framework of chiral perturbation theory at O(p(4)). We present photon spectra and partial decay rates for both processes as well as a Dalitz contour plot for the charged decay.
