This note is a presentation of an update of the measurements of the signal strengthsand couplings of the Higgs boson using the full 2011 and 2012 pp collision data samplerecorded by the ATLAS experiment at the LHC at 7 TeV, 8 TeV. Evidencefor direct decay into fermions is found at the 3.7 sigma.Measurements of production and decay mode specific signal strengths and Higgs boson couplingdeterminations in various benchmark models show good agreement with the StandardModel Higgs boson hypothesis.
