Abstract

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′ (Q 2 1 , Q2 2) in the momentum-transfer range 2< Q 2 1 , Q2 2 60 GeV 2 . 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.
