چکیده

An effective chiral theory of large NC QCD of mesons has been applied to study the form factor of πγγ∗. Besides the poles of vector mesons an intrinsic form factor is found. The slope of the form factor is predicted. The effect of the current quark masses on the decay rate is calculated. There is no adjustable parameter in this study.

Dispersion Relations and Sum Rules for the π 0 → γγ ∗ and γ ∗ → γπ 0 Form Factor

Sum rules for the off-shell isovector form factor π → γγ are given in terms of the pion form factor and the γπ → ππ experimental data. Similarly, the corresponding sum rules for the off-shell isoscalar form factor are given in terms of the experimental photon-3π form factor and the γπ → 3π amplitude. For some set of parameters, e.g Γ(ρ → πγ) ≃ 90KeV , the π → γγ rate and slope parameter of the ...

We calculate the one-quark-loop amplitude for the low energy γγ → ππ collision in the context of the Nambu and Jona-Lasinio model with scalar and pseudoscalar four quark couplings to all orders in the external momenta. We show that the NJL predictions for the γγ → π + π − reaction are not far from the Born amplitude, which is close to the data, and is compatible with the chiral perturbation the...

The decays π 0 , η, η ′ → γγ are investigated up to next-to-next-to leading order in the framework of the combined 1/N c and chiral expansions. Without mixing of the pseu-doscalar mesons the N c independence of the π 0 and η decay amplitudes is shown to persist at the one-loop level, although the contribution of the Wess-Zumino-Witten term to the pertinent vertices is not canceled by the N c de...

The neutral decay modes of the η meson are reviewed. The most recent results obtained with the Crystal Ball multiphoton detector at BNL are incorporated. This includes a new, precise result for the slope parameter α of the Dalitz plot in η → 3π 0 decay and a new, lower branching ratio for η → π 0 γγ which is consistent with chiral perturbation theory. Recently-obtained limits are given for nove...
