Chiral-loop and vector-meson contributions to eta -> pi pi gamma gamma decays
The process eta -> pi0 pi0 gamma gamma is discussed in Chiral Perturbation
Theory (ChPT) extending two recent analyses. Special attention is devoted to
one-loop corrections, eta-eta' mixing effects and vector-meson dominance of
ChPT counter-terms. The less interesting eta -> pi^+ pi^- gamma gamma
transition is briefly discussed too.Comment: 15 pages, 3 Postscript figures, uses epsfig.st
