Abstract
A search for the lepton-flavour violating decays B0 → K*0μ±e and B0s → ϕμ±e is presented, using proton-proton collision data collected by the LHCb detector at the LHC, corresponding to an integrated luminosity of 9 fb−1. No significant signals are observed. These results constitute the world’s most stringent limits to date, with the limit on the decay Bs0 → ϕμ±e the first being set. In addition, limits are reported for scalar and left-handed lepton-flavour violating New Physics scenarios.
