ee^+-->π^0γand form factor of π^0γ^*γ^*

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/43455The form factor π^0γ^*γ^* is obtained to the next leading order of derivative expansion of the chiral anomaly and the VMD. As a test the form factor has been used to calculate the cross section of ee^+-->π^0γ. Theory agrees with data.18 pages 5 figuresHigh Energy Physics - Phenomenologyee^+-->π^0γand form factor of π^0γ^*γ^*text
