Towards an improved understanding of $$\varvec{\eta \rightarrow \gamma ^*\gamma ^*}$$ η → γ ∗ γ ∗
Abstract We argue that high-quality data on the reaction $$e^+e^-\rightarrow \pi ^+\pi ^-\eta $$ e + e - → π + π - η will allow one to determine the doubly-virtual form factor $$\eta \rightarrow \gamma ^*\gamma ^*$$ η → γ ∗ γ ∗ in a model-independent way with controlled accuracy. This is an importan...
