Abstract
An analysis of the production of KS 0KS 0 and K±Ks 0π∓ by two quasi-real photons is presented. The cross section for γγ→K0 {Mathematical expression}, which is given for the γγ invariant mass range from K {Mathematical expression} threshold to 2.5 GeV, is dominated by the f′(1525) resonance and an enhancement near the K {Mathematical expression} threshold. Upper limits on the product of the two-photon width times the branching ratio into K {Mathematical expression} pairs are given for Θ(1700), h(2030), and ξ(2220). For exclusive two-photon production of K±Ks 0π∓ no significant signal was observed. Upper limits are given on the cross section of γγ→K+ {Mathematical expression}π- or K-K0π+ between 1.4 and 3.2 GeV and on the product of the γγ width times the branching ratio into the K {Mathematical expression}π final states for the ηc(2980) and the ι(1440), yielding Γ(γγ)→i(1440))·BR(i(1440)→K {Mathematical expression}π
