Search for B0 meson decays to π0KS0KS0, ηkS0KS0, and η′KS0KS0
We describe searches for B0 meson decays to the charmless final states π0KS0KS0, ηKS0KS0, and η′KS0KS0. The data sample corresponds to 467×106 BB̄ pairs produced in e+e- 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 10-7, B(B0→π0KS0KS0)<9, B(B0→ηKS0KS0)<10, and B(B0→η′KS0KS0)<20. © 2009 The American Physical Society.
