Abstract
Asearch is presented for a Higgs-like boson with
mass in the range 45 to 195 GeV/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, 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/c2 to 4 pb for a mass of 195 GeV/c2.
