摘要

En 中文

A dispersion integral is derived that connects data on eta ->pi (+) pi (-) gamma to the eta ->gamma gamma (au) transition form factor. A detailed analysis of the uncertainties is provided. We find for the slope of the eta transition form factor at the origin . Using an additional, plausible assumption, one finds for the corresponding slope of the eta' transition form factor, . Both values are consistent with all recent data, but differ from some previous theoretical analyses.
