Search for Standard Model Higgs boson in $H\to\tau^+\tau^-$ decay with the ATLAS detector
A searches for the Standard Model (SM) Higgs boson decaying into a pair of $\tau$ leptons are presented. The results are based on data samples of proton-proton collisions accumulated by ATLAS experiment at the LHC and corresponding to integrated luminosities of 4.6\,fb$^{-1}$ and 13.0\,fb$^{-1}$ at...

| description | A searches for the Standard Model (SM) Higgs boson decaying into a pair of $\tau$ leptons are presented. The results are based on data samples of proton-proton collisions accumulated by ATLAS experiment at the LHC and corresponding to integrated luminosities of 4.6\,fb$^{-1}$ and 13.0\,fb$^{-1}$ at center-of-mass energies of $\sqrt{s}=7$\,TeV and 8\,TeV, respectively. The observed (expected) upper limit at 95\% C.L. on the cross-section times the branching ratio for SM $H\to\tau^+\tau^-$ is found to be 1.9 (1.2) times the SM prediction for a Higgs boson with mass $m_H=125$\,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. |
