| dc.description.abstract | We study the reaction e + e − → e + e − π 0 in the single tag mode and measure the differential cross section d σ / d Q 2 and the γ γ ∗ → π 0 transition form factor in the momentum transfer range from 4 to 40 GeV 2 . At Q 2 > 10 GeV 2 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. | - |
