Inclusive K0sK0s resonance production in ep collisions at HERA

                 ZEUS Collaboration

Inclusive K0sK0s production in ep collisions at HERA was studied with the 
ZEUS detector using an integrated luminosity of 0.5 fb-1. Enhancements in 
the mass spectrum were observed and are attributed to the production of 
f2(1270)/a20(1320), f2'(1525) and f0(1710). Masses and widths were 
obtained using a fit which takes into account theoretical predictions 
based on SU(3) symmetry arguments, and are consistent with the PDG values.
The f0(1710) state, which has a mass consistent with a glueball candidate,
was observed with a statistical significance of 5 standard deviations.
However, if this state is the same as that seen in gamma gamma->K0sK0s, 
it is unlikely to be a pure glueball state.
