In this paper, we propose three different strategies to extract the weak mixing angle {phi}{sub s} of the B{sub s} system using penguin-mediated decays into vectors, mainly B{sub s}{yields}K*{sup 0}K*{sup 0}, B{sub s}{yields}{phi}K*{sup 0}, and B{sub s}{yields}{phi}{phi}. We also provide predictions for the longitudinal branching ratio and CP asymmetries of B{sub s}{yields}K*{sup 0}K*{sup 0} using a method that combines QCD factorization with flavor symmetries to relate this decay to its B{sub d} counterpart.
