Abstract: Recent evidence of the decay B→K+inv by Belle II show around a 2.7 sigma deviation from the standard model prediction. This measurement is explained with a dark scalar, S, that couples to the standard model particles and a massive sterile neutrino, N, which mixes with the active neutrinos. The flavor changing neutral current process B→KS→Kνbar{nu} then explains the Belle II measurement. The same set up can also explain the excess in electron like events observed in the MiniBooNE experiment and the muon g-2. I will discuss how the massive sterile neutrino can be probed in charged current B decays such as B→D^* l N at Belle II and at the FASER experiment.
