Measurement of inclusive K0sK0s resonance production with ZEUS at HERA

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 attributed to the production of 
f2(1270)/a20(1320), f2'(1525) and f0(1710). The f0(1710) state was observed 
with a 5sigma statistical significance. Masses and widths were obtained 
using a fit which takes into account theoretical predictions based on
SU(3) symmetry arguments.
