Abstract
The production of a kaon pair ( and ) in two-photon processes has been measured using the Belle detector at the electron-positron collider KEKB. We have obtained the invariant-mass distribution of the processes between 1.3 and 2.3 GeV. A broad bump structure around 1.7 GeV in the channel is confirmed, while, in the channel, a bump structure is seen near 1.9 GeV. The angular distribution of the final-state kaons is analyzed to explore the spin(-helicity) structure in each invariant-mass region for the two processes. Contributions from existing and postulated resonances are discussed.
