Measurements of properties of the Higgs boson in the diphoton decay channel with the full 2016 data set

Measurements of properties of the Higgs boson SM(125) in the $\mathrm{H}\rightarrow\gamma\gamma$ decay channel are reported. The analysis uses the data collected by the CMS experiment in proton-proton collisions during the 2016 LHC running period. The data sample corresponds to an integrated luminosity of $35.9\,\text{fb}^\text{$-$1}$ at ${\sqrt{s}=13\,\text{Te}\hspace{-.08em}\text{V}}$. The measured signal strength relative to the standard model prediction is ${1.16^{+0.15}_{-0.14}=1.16\ ^{+0.11}_{-0.10}\text{(stat.)}\ ^{+0.09}_{-0.08}\text{(syst.)}\ ^{+0.06}_{-0.05}\text{(theo.)}}$. Signal strengths associated with the different Higgs boson production mechanisms, coupling modifiers to bosons and fermions, and effective couplings to photons and gluons are also measured.
