Higgs searches at ATLAS

During July 2012, the ATLAS and CMS collaboration announced together the observation of a new boson in the Higgs searches, with a mass around 126 GeV. Since then, the Large Hadron Collider has been running steadly, providing proton-proton collisions at sqrt(s)=8 TeV; both experiments have now more than doubled the amount of data available since July. I will review the latest results of the ATLAS collaboration on Higgs searches, both in the Satandard-Model framework and beyond. I will present the available updated results with more analyzed data and refined analysis techniques with respect to summer 2012; the first results on 2012 data of Higgs searches to b-quarks and tau leptons final states will be presented as well.
