Abstract | A search for the Standard Model (SM) Higgs boson decaying into a pair of tau\tautau leptons is reported. The analysis, exploiting each of the tleptlep\tlep\tleptleptlep, tlepthad\tlep\thadtlepthad and thadthad\thad\thadthadthad final states, is based on data samples of proton-proton collisions collected by the ATLAS experiment at the LHC and corresponding to integrated luminosities of 4.6,ifb4.6\,\ifb4.6,ifb and 13.0,ifb13.0\,\ifb13.0,ifb at centre-of-mass energies of sqrts=7{\sqrt{s}=7 }sqrts=7 \TeV{} and 8,8\,8,\TeV{}, respectively. The observed (expected) upper limit at 95$\%$ CL on the cross-section times the branching ratio for SM Htotau+tau−H \to \tau^+\tau^-Htotau+tau− is found to be 1.9 (1.2) times the SM prediction for a Higgs boson with mass mHm_{H}mH=125 GeV. For this mass, the observed (expected) deviation from the background-only hypothesis corresponds to a local significance of 1.1 (1.7) standard deviations. |
