Abstract: KEK-KEKB. Measurement of the differential cross section of $\pi^0$ pair production in single-tag two-photon collisions. The cross section is measured for $Q^2$ up to 30 GeV$^2$ in the kinematic range 0.5 GeV < $W$ <2.1 GeV and $|\cos\theta^*|$<1.0. The results are based on a data sample of 759 fb$^{-1}$ collected with the Belle detector at the KEKB asymmetric-energy $e^+ e^-$ collider. The transition form factor of the $f_0(980)$ and that of the $f_2(1270)$ with the helicity-0, -1, and -2 components separately are measured.
