Two photon collisions at LEP: K/sub S//sup 0/K/sub S//sup 0/ final state, glueball searches and Lambda Lambda production

The exclusive K/sub S//sup 0/K/sub S//sup 0/ final state produced by two photon interactions is studied by the L3 experiment at LEP. The mass spectrum of the K/sub S//sup 0/K/sub S//sup 0/ system is dominated by resonance production the f/sub 2/ - a/sub 2/ interference, the f'/sub 2/(1525) tens...

Sumario:The exclusive K/sub S//sup 0/K/sub S//sup 0/ final state produced by two photon interactions is studied by the L3 experiment at LEP. The mass spectrum of the K/sub S//sup 0/K/sub S//sup 0/ system is dominated by resonance production the f/sub 2/ - a/sub 2/ interference, the f'/sub 2/(1525) tensor meson and a clear enhancement in the region around 1750 MeV. The spin and helicity of the two last states are determined. No signal is found at 2230 MeV. Also presented is the first measurement at LEP of the Lambda Lambda production in gamma gamma interactions.
