Here, we study the process e+e → e+eη' in the double-tag mode and measure for the first time the γ*γ* → η' transition form factor Fη'(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.
