Searches for B0 decays to ηK0, ηη, η′η′, ηϕ, and η′ϕ
We search for B 0 meson decays into two-body combinations of K 0 , η , η ′ , and ϕ mesons in 324 × 10 6 B ¯¯¯ B pairs collected with the BABAR detector at the PEP-II asymmetric-energy e + e − collider at SLAC. We measure the following branching fractions (upper limits at 90% confidence level) in uni...
