Query: Phenomenological Analysis of Charmless Decays Bs->PP,PV with QCD
  Factorization   We calculated the CP averaged branching ratios and CP-violating asymmetries
of two-body charmless hadronic Bs->PP,PV decays with the QCDF approach,
including the contributions from the chirally enhanced power corrections and
weak annihilations. Only several decay modes, such as Bs -> K^(*)K,
K^(*{\pm}){\pi}^{\mp}, K^{\pm}{\rho}^{\mp}, {\eta}^('){\eta}^('), have large
branching ratios, which may be observed in the near future. The penguin-to-tree
ratio P_{\pi \pi}/T_{\pi \pi} and a bound on angle ${\gamma}$ are given.
