## Search for lepton-flavour-violating decays of Higgs-like bosons

A search is presented for a Higgs-like boson with mass in the range 45 to 195 GeV/c(2) decaying into a muon and a tau lepton. The dataset consists of proton-proton interactions at a centre-of-mass energy of 8 TeV, collected by the LHCb experiment, corresponding to an integrated luminosity of 2 fb -1. The tau leptons are reconstructed in both leptonic and hadronic decay channels. An upper limit on the production cross-sectionmultiplied by the branching fraction at 95% confidence level is set and ranges from 22 pb for a boson mass of 45 GeV/c(2) to 4 pb for a mass of 195 GeV/c(2).
