Phys. Rev. D 68, 054003 (2003) [23 pages]Phenomenological analysis of charmless decays Bs→PP,PV with QCD factorizationReceived 11 November 2002; revised 3 March 2003; published 3 September 2003 We calculate the CP-averaged branching ratios and CP-violating asymmetries of two-body charmless hadronic decays of Bs→PP,PV with the QCD factorization approach (here P and V denote pseudoscalar and vector mesons, respectively), including contributions from the chirally enhanced power corrections and weak annihilations. Only several decay modes, such as Bs→K(*)K, K(*)±π∓, K±ρ∓, η(′)η(′), have large branching ratios, which may be observed in the near future. We also discuss Bs→K+K-, K0K0 decays which could overconstrain the penguin-to-tree ratio |Pππ/Tππ| of B⃗π+π- decays and give a bound on the Cabibbo-Kobayashi-Maskawa angle γ. © 2003 The American Physical Society URL:
