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 195GeV/c2GeV/c2\,{{\mathrm {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 TeV~{\mathrm {TeV}}, collected by the LHCb experiment, corres...

Description
Summary:A search is presented for a Higgs-like boson with mass in the range 45 to 195GeV/c2GeV/c2\,{{\mathrm {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 TeV~{\mathrm {TeV}}, collected by the LHCb experiment, corresponding to an integrated luminosity of 2 fb −1 fb −1\,\text{ fb }^{-1}. The tau leptons are reconstructed in both leptonic and hadronic decay channels. An upper limit on the production cross-section multiplied by the branching fraction at 95% confidence level is set and ranges from 22pbpb\,{\mathrm {pb}} for a boson mass of 45GeV/c2GeV/c2\,{{\mathrm {GeV/}}c^2} to 4pbpb\,{\mathrm {pb}} for a mass of 195GeV/c2GeV/c2\,{{\mathrm {GeV/}}c^2}.
