Measurements of the Standard Model Higgs parameters at ATLAS

Once the Higgs boson is discovered the focus will be shifted to uncovering its properties. Precision measurements of these parameters allow a deeper understanding of the electroweak symmetry-breaking mechanism. This paper summarizes the latest results on the measurement of the Higgs boson mass, total width, production rates, couplings to bosons and fermions, and spin. The results are given for an integrated luminosity of $300~fb^{-1}$.
