Abstracts

We report a measurement of differential cross section of?π0?pair production in single-tag two-photon collisions. These results are obtained with 759fb?1?of the data collected with the Belle detector at the KEKB asymmetric energy?e+e?collider. The cross section is measured for?Q2?up to 30 GeV2, where?Q2?is the negative of the invariant mass squared of the tagged virtual photon, in the kinematic range 0.5 GeV
