Measurements of the Higgs properties with Run 2 data in the bosonic channels
Recent results on the Higgs boson decays into WW$^\ast$, ZZ$^\ast$ and $\gamma \gamma$, obtained with the 2016 data collected by the CMS experiment, are presented. The decays into a pair of W bosons was observed with a significance of 9.1 sigma and has achieved a comparable precision in signal stren...

| Sumario: | Recent results on the Higgs boson decays into WW$^\ast$, ZZ$^\ast$ and $\gamma \gamma$, obtained with the 2016 data collected by the CMS experiment, are presented. The decays into a pair of W bosons was observed with a significance of 9.1 sigma and has achieved a comparable precision in signal strength compared to the other two channels. The Higgs boson mass has been measured in the channel with a pair of Z bosons decaying into four leptons as $m_\mathrm{H} = 125.26 \pm 0.20 (\mathrm{stat}) \pm 0.08 (\mathrm{syst}) = 125.26 \pm 0.21$ GeV, achieving the highest precision to-date. |
