Аннотация
We study the process e+e− → e+e−η0 in the double-tag mode and measure for the first time the γ?γ? → η0 transition form factor Fη0(Q21,Q22) in the momentum-transfer range 2 < Q21,Q22 < 60 GeV2. The analysis is based on a data sample corresponding to an integrated luminosity of around 469 fb−1 collected at the PEP-II e+e− collider with the BaBar detector at center-of-mass energies near 10.6 GeV.
