title = "Search for the lepton-flavour violating decays B 0 → K *0 µ ± e ± and B0s → Φµ ± e ±",
abstract = "A search for the lepton-flavour violating decays B-0 -> K-*0 mu e(-/+) and B-s(0)-> mu(+/-)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 and upper limits of[GRAPHICS].[GRAPHICS].[GRAPHICS].[GRAPHICS].are set at 90% (95%) confidence level. These results constitute the world's most stringent limits to date, with the limit on the decay B-s(0) -> phi mu(+/-) e(-/+) the first being set. In addition, limits are reported for scalar and left-handed lepton-flavour violating New Physics scenarios.",
