Abstract

The (KSKS0)-K-0 final state in two-photon collisions is studied with the L3 detector at LEP. The mass spectrum is dominated by the formation of the f'(2)(1525) tensor meson in the helicity-two state with a two-photon width times the branching ratio into K (K) over bar of 76 +/- 6 +/- 11 eV. A clear signal for the formation of the f(J)(1710) is observed and it is found to be dominated by the spin-two helicity-two state. No resonance is observed in the mass region around 2.2 GeV and an upper limit of 1.4 eV at 95% C.L. is derived for the two-photon width times the branching ratio into (KSKS0)-K-0 for the glueball candidate xi (2230).
