    A bstract A search for the decay B S 0 → K ¯ ∗ 0 μ + μ − is presented using data sets corresponding to 1.0, 2.0 and 1.6 fb −1 of integrated luminosity collected during pp collisions with the LHCb experiment at centre-of-mass energies of 7, 8 and 13 TeV, respectively. An excess is found over the background-only hypothesis with a significance of 3.4 standard deviations. The branching fraction of the B S 0 → K ¯ ∗ 0 μ + μ − decay is determined to be ℬ B s 0 → K ¯ ∗ 0 μ + μ − = 2.9 ± 1.0 stat ± 0.2 syst ± 0.3 norm × 10 − 8 , where the first and second uncertainties are statistical and systematic, respectively. The third uncertainty is due to limited knowledge of external parameters used to normalise the branching fraction measurement.
