Analysis of $B^0_{(s)}\toμ^+μ^-$ decays at the LHC

This article reviews the most recent measurements of $B_{(s)}^0\toμ^+μ^-$ decay properties at the LHC, which are the most precise to date. The measurements of the branching fraction and effective lifetime of the $B_{s}^0\toμ^+μ^-$ decay by the ATLAS, CMS and LHCb collaborations, as well as the search for $B^0\toμ^+μ^-$ 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.
