Analysis of $B_{(s)}^0\to {\mu }^{+}{\mu }^{-}$ decays at the LHC

This article reviews the most recent measurements of $B_{(s)}^0\to {\mu }^{+}{\mu }^{-}$ decay properties at the LHC, which are the most precise to date. The measurements of the branching fraction and effective lifetime of the $B_s^0\to {\mu }^{+}{\mu }^{-}$ decay by the ATLAS, CMS and LHCb collaborations, as well as the search for $B^0\to {\mu }^{+}{\mu }^{-}$ decays are summarised with a focus on the experimental challenges. Furthermore prospects are given for these measurements and new observables that become accessible with the foreseen amounts of data by the end of the LHC.
