Search for the lepton-flavour violating decays B$^{0}$→ K$^{0}$μ$^{±}$e$^{∓}$ and $ {B}_s^0 $→ ϕμ$^{±}$e$^{∓}

Search for the lepton-flavour violating decays B$^{0}$→ K$^{0}$μ$^{±}$e$^{∓}$ and $ {B}_s^0 $→ ϕμ$^{±}$e$^{∓}

A search for the lepton-flavour violating decays B$^{0}$ → K$^{*0}$μ$^{±}$e$^{∓}$ and $ {B}_s^0 $→ ϕμ$^{±}$e$^{∓}$ 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...
