چکیده
Vector-Meson-Dominance model contribution to π 0 → 4γ is calculated. The result confirms old estimates that this contribution is much smaller than the purely electromagnetic photon spliting graph contribution calculated earlier. In the framework of the Vector-Meson-Dominance (VMD) model, the decay π 0 → 4γ was considered in [1] and [2]. However, no complete evaluation of the decay width can be found in these papers, because the calculations are too tedious to be performed by hand.

We use recent data on K + → π + e + e − , together with known values for the pion form factor, to derive the kaon electromagnetic form factor for 0 < q 2 < 0.125 (GeV/c) 2. The results are then compared with predictions of the Linear σ Model, a quark-triangle model and Vector Meson Dominance. The first two models describe the data at least qualitatively, but the simple Vector Meson Dominance pi...

We improve the calculations of the η → π 0 γγ decay within the context of me-son chiral lagrangians. We use a chiral unitary approach for the meson-meson interaction, thus generating the a 0 (980) resonance and fixing the longstanding sign ambiguity on its contribution. This also allows us to calculate the loops with one vector meson exchange, thus removing a former source of uncertainty. In ad...

Predictions based on the chirally normalized vector meson dominance model for decay rates and distributions of τ decays into Kππντ final states are discussed. Disagreements with experimental results can be traced back to the K1 widths. Hadronic τ decays into final states with kaons can provide detailed information about low energy hadron physics in the strange sector. Predictions for final stat...

We consider the scalar form factor in the weak current matrix element < PK|jμ|0 >, P = π, η, η′. It obtains the contributions from the scalar meson resonance K∗ 0(1430) and from the scalar projection of the vector meson K∗(892) resonance. We analyze decay amplitudes of the Cabibbo suppressed decays D → KP , P = π, η, η′ using the factorization approach. The form factors of the relevant matrix e...
