Abstract: | We describe searches for B 0 meson decays to the charmless final states π 0 K 0 S K 0 S , η K 0 S K 0 S , and η ′ K 0 S K 0 S . The data sample corresponds to 467 × 10 6 B ¯¯¯ B 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 ( B 0 → π 0 K 0 S K 0 S ) < 9 , B ( B 0 → η K 0 S K 0 S ) < 10 , and B ( B 0 → η ′ K 0 S K 0 S ) < 20 . |
