In this paper, we propose three different strategies to extract the weak mixing angle s of the Bs system using penguin-mediated decays into vectors, mainly Bs→K*0K̄*0, Bs→ K̄*0, and Bs→. We also provide predictions for the longitudinal branching ratio and CP asymmetries of Bs→K*0K̄*0 using a method that combines QCD factorization with flavor symmetries to relate this decay to its Bd counterpart. © 2007 The American Physical Society.
