Measurements of the Higgs boson properties with the ATLAS detector

The measurements of the properties of a new boson discovered by the ATLAS experiment at the LHC are presented, based on proton-proton collision data collected in 2011 and 2012. The production strengths and the couplings are measured using decays of the new boson into $\gamma \gamma$, $ZZ^{*} \righta...

description The measurements of the properties of a new boson discovered by the ATLAS experiment at the LHC are presented, based on proton-proton collision data collected in 2011 and 2012. The production strengths and the couplings are measured using decays of the new boson into $\gamma \gamma$, $ZZ^{*} \rightarrow 4 \ell$, and $WW^{*} \rightarrow \ell\nu\ell\nu$. The spin-0 and CP-even ($J^P=0^+$) hypothesis of the standard model~(SM) Higgs boson is compared to several alternative hypotheses with $J^P =$ $0^-$, $1^+$, $1^-$, $2^+$ using decays of the new boson into $\gamma \gamma$, $ZZ^{*} \rightarrow 4 \ell$, and $WW^{*} \rightarrow e\nu\mu\nu$. The measured properties are compatible with the SM Higgs boson.
