Abstract
We study the reactions e+e-→e+e -η(′) in the single-tag mode and measure the γγ*→η(′) transition form factors in the momentum-transfer range from 4 to 40GeV2. The analysis is based on 469fb-1 of integrated luminosity collected at PEP-II with the BABAR detector at e+e- center-of-mass energies near 10.6 GeV. © 2011 American Physical Society.
