Measurement of the γγ^*→η and γγ^*→η^′ transition form factors
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 40 GeV^2. The analysis is based on 469 fb^(-1) of integrated luminosity collected at PEP-II with the BABAR detector at e^+e^- center-of-mass energies near 10.6 GeV.
