Search for B-0 meson decays to pi(KSKS0)-K-0-K-0, eta(KSKS0)-K-0, and eta(KSKS0)-K-'-K-0

We describe searches for B-0 meson decays to the charmless final states pi(KSKS0)-K-0-K-0, eta(KSKS0)-K-0, and eta(KSKS0)-K-'-K-0. The data sample corresponds to 467x10(6) BB 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 ->pi(KSKS0)-K-0-K-0) eta(KSKS0)-K-0) eta(KSKS0)-K-'-K-0)< 20.
