The (KsKs0)-K-0 final state in two-photon collisions and glueball searches

The (KsKs0)-K-0 final state in two-photon collisions is studied with the L3 detector at LEP using data collected at centre of mass energies from 91 Ge V to 189 GeV, The spectrum is dominated by the formation of the f(2)(')(152 5) tensor meson in helicity two state. Clear evidence for a destructive f(2 ) - a(2) interference is observed. A clear peak of about 7 standard deviati ons is present around the 1750 MeV. It can be due to the formation of a 0(+) or 2(++) state. No signal has been observed in the region around 2.2 GeV . An upper limit for the two-photon partial width of the xi(2230) glueball candidate is then derived.
