Abstract

We study the reaction e+e-→e+e-π0 in the single tag mode and measure the differential cross section dσ/dQ2 and the γγ*→π0 transition form factor in the momentum transfer range from 4 to 40 GeV2. At Q2>10 GeV2 the measured form factor exceeds the asymptotic limit predicted by perturbative QCD. The analysis is based on 442 fb-1 of integrated luminosity collected at PEP-II with the BABAR detector at e+e- center-of-mass energies near 10.6 GeV.
