Combined Measurements of the Properties of the Higgs Boson Using the ATLAS Detector

The couplings of the Higgs boson are presented, as measured at the ATLAS detector at the LHC. The measurements are made with 5/fb of pp collisions at $\sqrt{s}$ = 7 TeV and 20/fb of collisions at $\sqrt{s}$ = 8 TeV. A combination is made betwen the $h \to \gamma\gamma$, $h \to ZZ^*$, $h\to WW^*$, $h\to b\bar b$, and $h \to \tau \tau$ channels. Results include the ratios of fermionic and vector couplings to the Higgs boson, a measurement of the custodial symmetry in the Higgs sector, and a limit on invisible or unobserved decays.
