Lepton flavor universality in rare $b \to s$ transitions is tested for the first time using $B_{s}^{0}$ meson decays. The measurements are performed using $p p$ collision data collected by the LHCb experiment between 2011 and 2018, corresponding to a total integrated luminosity of $9 {fb}^{- 1}$ . Branching fraction ratios between the $B_{s}^{0} \to ϕ e^{+} e^{-}$ and $B_{s}^{0} \to ϕ μ^{+} μ^{-}$ decays are measured in three regions of dilepton mass squared, $q^{2}$ , with $0.1 < q^{2} < 1.1$ , $1.1 < q^{2} < 6.0$ , and $15 < q^{2} < 19 {GeV}^{2} / c^{4}$ . The results agree with the standard model expectation of lepton flavor universality. © 2025 CERN, for the LHCb Collaboration 2025 CERN
