The data sample corresponds to an integrated luminosity of 1.0 fb(-1) of proton-proton collisions at a centre-of-mass energy of 7 TeV and 2.0 fb(-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(tau(-) -> mu(-)mu(+)mu(-)) < 4.6 x 10(-8).", optnote="WOS:000350332500001", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=2148), last updated on Thu, 02 Apr 2015 11:45:06 +0000", issn="1029-8479", doi="10.1007/JHEP02(2015)121", opturl="http://arxiv.org/abs/1409.8548", opturl="https://doi.org/10.1007/JHEP02(2015)121", archivePrefix="arXiv", eprint="1409.8548", language="English" }
