Abstract
A search for the lepton-flavor violating decays 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 . No significant signal is observed, and upper limits on the branching fractions are set as and at 90% (95)% confidence level. The results improve the current best limits on these decays by more than one order of magnitude.
