| 英文摘要 | (ksks0)-k-0 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 cos theta*vertical bar < 0.6. combining the results with measurements of gamma gamma -> k+k- from belle, we observe that the cross section ratio sigma((ksks0)-k-0)/sigma(k+k-) decreases from similar to 0.13 to similar to 0.01 with increasing energy. signals for the chi(c0) and chi(c2) charmonium states are also observed.
