$B_{s}^{0} \to \mu^{+}\mu^{-}$ in LHCb

Due to its sensitivity to New Physics contributions, the branching ratio of the very rare decay $B_{s}^{0}\rightarrow\mu^{+}\mu^{-}$ is one of the most interesting measurements using the first data from the LHC accelerator. In this article, the analysis strategy for the study of this channel in the LHCb experiment is presented, as well as a review of the potential of the experiment in such study, using the latest simulations. With 3-4 months of nominal data taking, any enhancement from the Standard Model prediction can be excluded.
