DOIAbstract
We report a high-statistics measurement of the differential cross section of the process γγ → K0 SK0 S in the range 1.05 GeV ≤ W ≤ 4.00 GeV, where W is the center-of-mass energy of the colliding photons, using 972 fb-1 of data collected with the Belle detector at the KEKB asymmetric-energy e +e- collider operated at and near the ρ-resonance region. The differential cross section is fitted by parameterized S-, D 0-, D2-, G0-, and G2-wave amplitudes. In the D2 wave, the f2(1270), a 2(1320), and f2 ′(1525) are dominant and a resonance, the f2(2200), is also present. The f0(1710) and possibly the f0(2500) are seen in the S wave. The mass, total width, and product of the two-photon partial decay width an...
