【 摘 要 】

We present an updated search for the Standard Model Higgs boson in the H → b and H → τ+τ-decay modes performed by the ATLAS experiment using 4.7 fb1of LHC data at √TeV and 13.0 fb-1at √TeV delivered in 2011 and 2012 respectively. No significant excess is observed. For mH= 125 GeV the observed (expected) upper limit at 95% confidence level on the cross section times the branching ratio is found to be 1.8 (1.9) times the Standard Model prediction for H → bb¯ and 1.9 (1.2) for H → τ+τ-.
