Abstract

We study B_s → KK decays in the framework of the PQCD. We show that the branching ratios of B_s → (K⁺K^-, K⁰K̄⁰) are about (22.43, 25.78) × 10^-6 for φ₃(γ) ≃ 72°, which are consistent with the model-independent estimations. We find that the typical scale of the decays is near 1.7 GeV. We also point out that the induced strong phase δ is around 207° so that the direct CP asymmetry of B_s → K⁺K^- could reach 15%.
