Observation of K0(s) K0(s) resonances in deep inelastic scattering at HERA

Inclusive KsKs production in deep inelastic ep scattering at HERA has been studied with the ZEUS detector using an integrated luminosity of 120 pb-1. Two states are observed at masses of 1537 (+9)(-8) MeV and 1726 +- 7 MeV, as well as an enhancement around 1300 MeV. The state at 1537 MeV is consistent with the well established f2'(1525). The state at 1726 MeV may be the glueball candidate f0(1710). However, it's width of 38 (+20)(-14) MeV is narrower than 125 +- 10 MeV observed by previous experiments for the f0(1710).
