Search for the lepton-flavor-violating decays Bs0→e ±μ and B0→e±μ

Journal article

A search for the lepton-flavor-violating decays Bs0→e ±μ and B0→e±μ is performed with a data sample, corresponding to an integrated luminosity of 1.0 fb-1 of pp collisions at √s=7 TeV, collected by the LHCb experiment. The observed number of Bs0→e±μ and B0→e ±μ candidates is consistent with background expectations. Upper limits on the branching fractions of both decays are determined to be B(Bs0→e±μ)<1.1(1.4)×10-8 and B(B0→e±μ)<2.8(3.7)×10-9 at 90% (95%) confidence level (C.L.). These l...
