| Samenvatting | Inclusive (KSKS0)-K-0 production in ep collisions at the DESY ep collider 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 f(2)(1270)/a(2)(0)(1320), f(2)(')(1525) and f(0)(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 Particle Data Group values. The f(0)(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 -> (KSKS0)-K-0, it is unlikely to be a pure glueball state. |
