| Summary: | A search for the lepton flavour violating decay τ [superscript −] → μ [superscript −] μ [superscript +] μ [superscript −] is performed with the LHCb experiment. The data sample corresponds to an integrated luminosity of 1.0 fb[superscript −1] of proton-proton collisions at a centre-of-mass energy of 7 TeV and 2.0 fb[superscript −1] at 8 TeV. No evidence is found for a signal, and a limit is set at 90% confidence level on the branching fraction, B(τ [superscript −] → μ [superscript −] μ [superscript +] μ [superscript −]) < 4.6 × 10[superscript −8]. |
