| contents | Belle II has reported the first evidence for $B^+ \to K^+ν\barν$ with a branching ratio $2.7 σ$ higher than the standard model expectation. We explain this, and the MiniBooNE and muon anomalous magnetic moment anomalies in a model with a dark scalar that couples to a slightly heavier sterile Dirac neutrino and that communicates with the visible sector via a Higgs portal. We make predictions for rare kaon and other $B$ meson decays. |
