EMPHASIZING THE DIFFERENT TRENDS OF THE EXISTING DATA FOR THE γ*γ → π0 TRANSITION FORM FACTOR

The new data on the gamma*gamma -> pi(0) transition form factor of the Belle Collaboration are analyzed in comparison with those of BaBar (including the older data of CELLO and CLEO) using an approach based on lightcone sum rules. Performing a 2-, and a 3-parametric fit to these data, we found that the Belle and the BaBar data have no overlap at the 1 sigma level. While the Belle data agree with our predictions, the Babar data are in conflict with them.
