Abstract: (APS)

We report a measurement of the differential cross section of π0 pair production in single-tag two-photon collisions, γ*γ→π0π0, in e+e- scattering. The cross section is measured for Q2 up to 30 GeV2, where Q2 is the negative of the invariant mass squared of the tagged photon, in the kinematic range 0.5 GeV
