Description
KS0KS0 production in two-photon collisions has been studied using a 397.6 fb-1 data sample collected with the Belle detector at the KEKB e+e- collider. For the first time the cross sections are measured in the two-photon center-of-mass energy range between 2.4 GeV and 4.0 GeV and angular range vertical bar cosθ* vertical bar <0.6. Combining the results with measurements of γγ->K+K- from Belle, we observe that the cross section ratio σ(KS0KS0)/σ(K+K-) decreases from ∼0.13 to ∼0.01 with increasing energy. Signals for the χc0 and χc2 charmonium states are also observed
