ee^+-->π^0γand form factor of π^0γ^*γ^*
Bing An Li
The 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…

Correction of the low energy theorem of γ\to2πanomaly
Bing An Li
A correction of the low energy theorem of the γ\to3πanomaly has been found. A_{3π}(0,0,0) and the cross section are calculated. Theory agrees with data. There is no new adjustable…
