TL;DR

This paper reports on searches for B meson decays to eta' eta' K final states using a large dataset, setting upper limits on their branching fractions.

Contribution

First search for B meson decays to eta' eta' K final states, providing upper limits on their branching fractions based on extensive data.

Findings

No significant signals observed for the decays.

Upper limits set at 90% confidence level for branching fractions.

Results constrain theoretical models of B meson decays.

Abstract

We describe searches for decays of B mesons to the charmless final states eta' eta' K. The data consist of 228 million B Bbar pairs produced in e+ e- annihilation, collected with the BaBar detector at the Stanford Linear Accelerator Center. The 90% confidence level upper limits for the branching fractions are Br(B0->eta' eta' K0)<31 10^{-6} and Br(B+->eta' eta' K+)<25 10^{-6}.
