Abstract

We have searched for resonance production in the reaction γγ→Ks 0Kπ. No signal was found for the ηc and an upper limit for the radiative with {Mathematical expression} keV (95% c.l.) is obtained. For the glueball candidate η(1440) (previously i) the upper limit {Mathematical expression} is derived. In the tagged data sample resonance formation of a spin 1 state at 1420 MeV is observed, which is absent in the untagged data. The mass and width of this state are consistent with those of the f1(1420); an analysis of decay angular distributions favours positive parity.
