  1. Introduction: a) motivations, b) status, c) purpose, d) results 2. Kinematics and couplings 3. Decay amplitude (analytic expression): a) tree level, b) one loop 4. Decay width (numerical): a) diphoton energy spectrum [energy cut] 5. Discussion: detectability of chiral loop effects (background suppression)
