Search for B^{0} meson decays to pi^{0}K_{S}^{0}K_{S}^{0}, eta K_{S}^{0}K_{S}^{0}, and eta^{'}K_{S}^{0}K_{S}^{0}

Abstract

We describe searches for B[superscript 0] meson decays to the charmless final states π[superscript 0]K[subscript S][superscript 0]K[subscript S][superscript 0], ηK[subscript S][superscript 0]K[subscript S][superscript 0], and η′K[subscript S][superscript 0]K[subscript S][superscript 0]. The data sample corresponds to 467×10[superscript 6] BB̅ pairs produced in e[superscript +]e[superscript -]annihilation and collected with the BABAR detector at the SLAC National Accelerator Laboratory. We find no significant signals and determine the 90% confidence level upper limits on the branching fractions, in units of 10[superscript -7], B(B[superscript 0]→π[superscript 0]KS[superscript 0]KS[superscript 0])<9, B(B0→ηK[superscript S][subscript 0]K[subscript S][superscript 0])<10, and B(B[superscript 0]→η′K[subscript S][superscript 0]K [subscript S][superscript 0])<20.
