title = "Search for Lepton-Flavor Violating Decays B+ →k+μ±e{\^a}{"}",
abstract = "A search for the lepton-flavor violating decays B+→K+μ±e{\^a}{"} is performed using a sample of proton-proton collision data, collected with the LHCb experiment at center-of-mass energies of 7 and 8 TeV and corresponding to an integrated luminosity of 3 fb-1. No significant signal is observed, and upper limits on the branching fractions are set as B(B+→K+μ-e+)<7.0(9.5)×10-9 and B(B+→K+μ+e-)<6.4(8.8)×10-9 at 90\% (95)\% confidence level. The results improve the current best limits on these decays by more than one order of magnitude.",
