Revisiting the annihilation decay $\bar{B}_{s} \to \pi^+\pi^{-}$

It is very important to know the strength of the annihilation contribution in B charmless non-leptonic decays. The B/sub s /macronrightward arrowpi/sup positive pi; /sup negative process could serve as a good probe of the strength. We have studied the process in the QCD factorization framework. Usin...
