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

The European Physical Journal C - Particles and Fields. 2018. Vol. 78. No. 12. P. 1-12.

A search is presented for a Higgs-like boson with mass in the range 45 to 195 GeV/𝑐2GeV/c2 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 , collected by the LHCb experiment, corresponding to an integrated luminosity of 2  fb −1 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 22 pbpb for a boson mass of 45 GeV/𝑐2GeV/c2 to 4 pbpb for a mass of 195 GeV/𝑐2GeV/c2 .
