Abstract

We describe searches for decays of B mesons to the charmless final states \ensuremathη^\ensuremath'\ensuremathη^\ensuremath'K. The data consist of 228\ifmmode×\else\texttimes\fi10⁶ BB pairs produced in e⁺e^\ensuremath- annihilation, collected with the BABAR detector at the Stanford Linear Accelerator Center. The 90% confidence level upper limits for the branching fractions are B(B⁰\ensuremath→\ensuremathη^\ensuremath'\ensuremathη^\ensuremath'K⁰)<31\ifmmode×\else\texttimes\fi10^\ensuremath-6 and B(B⁺\ensuremath→\ensuremathη^\ensuremath'\ensuremathη^\ensuremath'K⁺)<25\ifmmode×\else\texttimes\fi10^\ensuremath-6.
