Partial Wave Analysis of the Centrally ProducedKSKSSystem at800GeV/c

Results are presented from a partial wave analysis of a sample of centrally produced mesons in the reaction $\mathrm{pp}\to p_{\mathrm{slow}}\left(K_S{K}_S\right)p_{\mathrm{fast}}$, with 800 GeV/c protons incident on a liquid hydrogen target. The meson system is found to be predominantly $S$ wave in the mass range between $K_S{K}_S$ threshold and $1.55\mathrm{GeV}{/c}^2$. The $f_0\left(1500\right)$ is observed in this region. Above $1.55\mathrm{GeV}{/c}^2$ two solutions are possible, one with mainly $S$ wave and another with mainly $D$ wave. This ambiguity prevents a unique determination of the spin of the $f_J\left(1710\right)$ meson.
