Chiral–loop and Vector–meson Contributions to Η → Ππγγ Decays
The process η → π 0 π 0 γγ is discussed in Chiral Perturbation Theory (ChPT). Special attention is devoted to one-loop corrections, η-η ′ mixing effects and vector-meson dominance of ChPT counter-terms. The less interesting η → π + π − γγ transition is briefly discussed too. The rare decay modes η → π 0 π 0 γγ and η → π + π − γγ have been recently discussed by several authors in the context of ...
متن کاملη → π 0 γγ decay in the three - flavor Nambu – Jona - Lasinio model
We study the η → π 0 γγ decay via the quark-box diagram in the three-flavor Nambu–Jona-Lasinio model that includes the U A (1) breaking effect. We find that the η-meson mass, the η → γγ decay width and the η → π 0 γγ decay width are in good agreement with the experimental values when the U A (1) breaking is strong and the flavor SU (3) singlet-octet mixing angle θ is about zero. The photon ener...
متن کاملγγ decay within a chiral unitary approach
Together with the VMD dominant terms for η → π 0 γγ, we introduce the contribution of chiral loops from unitarized chiral perturbation theory, thus generating the a 0 (980) resonance and fixing the longstanding sign ambiguity on its contribution to this process. The same approach allows us to establish constraints in the decay from the γγ → π 0 η data. In particular, the ηV V couplings have to ...

The radiative decays of the pseudoscalar mesons P = (π 0 , η, η ′) are of special interest as they provide an experimental window on the electromagnetic and colour chiral UA(1) anomalies. π 0 → γγ is well described by the electromagnetic UA(1) anomaly under the assumption that π 0 is a Goldstone boson for spontaneously broken chiral symmetry, but the analogous results for η ′ (η) → γγ are compl...

Calculations of η → ππγγ decay in Generalized chiral perturbation theory are presented. Tree level and next-to-leading corrections are involved. Sensitivity to violation of the Standard counting is discussed.
