Search for the Standard Model Higgs boson in the H → b b-bar and H → τ+τ− decay modes with the ATLAS detector

We present an updated search for the Standard Model Higgs boson in the H → b b-bar and H → τ+τ− decay modes performed by the ATLAS experiment using 4.7 fb1of LHC data at √s = 7 TeV and 13.0 fb at √s = 8 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 → b b-bar and 1.9 (1.2) for H → τ+τ−
