N2 - We provide a set of sum rules, using flavor symmetries, relating CP-averaged ratios and CP asymmetries of different neutral and charged B mesons decaying into an η(′) particle together with a pion, a kaon or a second η(′). These sum rules allow us to give a prediction for the B0 → K0 η branching ratio. We also predict a clear sign anti-correlation between the two B0 → π0 (η, η′) CP asymmetries, and find a combined constraint on the branching ratios and CP asymmetries of the three B → η(′) η(′) decay modes. © 2007 Elsevier B.V.
