Search for B decays into η′p, η′K*, η′, η′ω and η′η(′)

Abstract

We report on a search for the exclusive two-body charmless hadronic B meson decays B→η′ρ, B→η′K*, B0→η′, B0→η′ω, and B0→η′η (′). The results are obtained from a data sample containing 535×106 BB̄ pairs that were collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We find no significant signals and report upper limits in the range (0.5-6.5)×10-6 for all of the above decays. © 2007 The American Physical Society.
