摘要：

K (+) K- production in two-photon collisions has been studied using a large data sample of 67 fb(-1) accumulated with the Belle detector at the KEKB asymmetric e (+) e(-) collider. We have measured the cross section for the process gammagamma --> K+K- for center-of-mass energies between 1.4 and 2.4 GeV, and found three new resonant structures in the energy region between 1.6 and 2.4 GeV. The angular differential cross sections have also been measured.
