Two-photon interactions at Belle and BaBar

Eidelman Simon

Results on two-photon physics obtained in experiments at the B factories are discussed. BaBar used single-tag γγ collisions to measure the transition form factor of the π0 meson. Belle studied no-tag γγ collisions to measure cross sections of exclusive production of two baryons and two mesons. Experimental results are confronted with QCD predictions.
